Best Waterproof Jackets UK 2025

8 Expert-Tested Options for British Weather

1. Introduction: Surviving the Great British Downpour

Finding the best waterproof jackets UK 2025 has to offer is non-negotiable for British hiking. After testing 8 jackets through 600+ kilometres of Lake District downpours, Scottish Highland gales, and Snowdonia horizontal rain, I learned that ‘waterproof’ ratings mean nothing if breathability fails, and the £500 Arc’teryx isn’t always better than the £150 Rab. Ultimately, performance in real-world conditions is key, and understanding features like zippers, seams, and fabric technology can greatly impact your experience. For those looking to enhance their outdoor adventures, incorporating wild camping tips for beginners can make all the difference in enjoying the great outdoors. Remember, the right gear not only keeps you dry but also maximizes comfort, allowing for a more enjoyable experience in unpredictable British weather.

The UK’s climate is famously fickle. With over 200 rain days a year in many of our most beautiful hiking spots, a reliable waterproof jacket isn’t just a piece of kit; it’s your primary defence against misery and, in serious conditions, hypothermia. But the market is a minefield of technical jargon: Hydrostatic Head, MVTR, GORE-TEX, Pertex Shield, 2.5-layer, 3-layer. It’s easy to spend a fortune and still end up soaked, not from rain getting in, but from your own sweat having no escape.

This guide cuts through the marketing noise. I’ve pushed these jackets to their limits on strenuous ascents like Helvellyn via Striding Edge and long, boggy slogs in the Cairngorms. I’ve evaluated them not just on their ability to keep torrential rain out, but on how they manage internal moisture when you’re working hard, how their hoods cope with 60mph gusts, and how they feel after 8 hours on the trail. We’ll explore why features like pit zips are essential for UK hillwalking, why a 20,000mm waterproof rating is the benchmark you should aim for, and how to choose a jacket that balances weight, durability, and price for your specific needs. Whether you’re a weekend walker or a seasoned mountaineer, this guide will help you invest wisely and stay dry, comfortable, and safe on your next British adventure.

Rab Downpour Plus 2.0: Best Overall UK Jacket

UK Performance Testing

The Rab Downpour Plus 2.0 was my workhorse jacket, tested extensively on the West Highland Way during a particularly wet May and on multiple ascents in the Brecon Beacons. In classic British fashion, conditions ranged from persistent drizzle to full-blown deluges. The 2.5-layer Pertex Shield fabric, with its 20,000mm rating, held up flawlessly, keeping me bone dry even after 6+ hours of driving rain in Patagonia, as one reviewer noted. Where it truly excelled for UK hiking was its breathability. On the steep climb up Pen y Fan, I expected to get clammy, but the 20,000g/m² MVTR rating, combined with the generous pit zips, allowed for excellent temperature regulation. While some users report the DWR ‘wetting out’ faster than premium 3-layer jackets, the membrane never let water through. It strikes the perfect balance for the UK: robust enough for mountain weather, breathable enough for the inevitable sweaty climbs, and packable enough to live in your rucksack.

Pros

• Excellent waterproof and breathability stats (20k/20k) for the price.
• Generous pit zips provide crucial ventilation for UK climbs.
• Helmet-compatible hood with a stiff polymer peak and excellent adjustability, holding firm in strong winds.
• Made with recycled fabrics and a fluorocarbon-free DWR, boosting its eco-credentials.
• Lightweight and highly packable, doubling as its own stuff sack.
• Great fit with articulated sleeves, allowing for easy layering and movement.

Cons

• 2.5-layer construction is less durable against abrasion than 3-layer jacket.
• DWR finish can ‘wet out’ in prolonged downpours, making the jacket feel cold and heavy, though it doesn’t leak.
• Some users find the AquaGuard zips a little snaggy.

Best for the vast majority of UK hillwalkers and backpackers who need a reliable, breathable, and well-featured jacket that offers outstanding performance without the premium price tag.Check Price on Amazon UK Pair this jacket with the best hiking socks in the UK to ensure maximum comfort and performance on your outdoor adventures. Designed to wick moisture and keep your feet warm, these socks complement the jacket’s breathable qualities perfectly. Together, they create an ideal setup for tackling any terrain, whether you’re on a short day hike or a challenging multi-day trek.

Montane Phase: Best Lightweight Jacket

UK Performance Testing

The Montane Phase is a masterclass in lightweight, no-fuss protection. I tested the ‘Phase Lite’ version (around 285g) on fast-and-light days in the Peak District, including a soggy traverse of Kinder Scout. Its GORE-TEX fabric is utterly dependable, shrugging off sideways rain with ease. The key advantage is its breathability; even without the pit zips of the heavier standard ‘Phase’ model, the GORE-TEX Active membrane in the Lite version did a remarkable job of managing moisture during scrambles. The standard Phase (430g) uses a more durable 40D GORE-TEX Performance fabric and includes pit zips, making it a more robust all-rounder. On test, the standard Phase felt bombproof during a winter skills course in the Cairngorms, its 28,000mm rating providing total confidence. The hood on both versions is excellent, with a stiffened peak and three-point adjustment that cinches down securely. It’s a jacket for those who prioritise breathability and low weight without compromising on GORE-TEX’s proven waterproofing.

Excellent waterproofing with a 28,000mm GORE-TEX membrane.Highly breathable (RET <9), especially the ‘Lite’ version with GORE-TEX Active.Superb fully adjustable hood with a stiffened peak that holds up in wind.Lightweight and packable, ideal for stashing in a rucksack.Durable face fabrics (40D or 70D depending on model) stand up to trail use.Good eco-credentials with recycled fabrics and PFC-free DWR.

Cons

• The ‘Lite’ version lacks pit zips, which some may miss.
• Fit is on the slimmer side, so consider sizing up for heavy winter layering.
• GORE-TEX fabric can feel ‘crinkly’ compared to softer proprietary fabrics.

Best for hikers and mountaineers who want premium GORE-TEX performance in a lightweight, breathable, and well-designed package for year-round use.Check Price on Amazon UK

Berghaus Paclite 2.0: Best Budget GORE-TEX

UK Performance Testing

The Berghaus Paclite 2.0 is the gateway to GORE-TEX ownership for many UK walkers, and for good reason. I used this jacket for countless dog walks in the notoriously damp Forest of Bowland and as my emergency shell on summer hikes in the Yorkshire Dales. Its key strength is its incredible packability; it rolls down to the size of a large tin of beans and weighs next to nothing, so there’s no excuse to leave it at home. The GORE-TEX Paclite membrane provides guaranteed waterproofing, and it kept me dry through many sudden and heavy downpours. However, the trade-off for its low weight and price is breathability. On steeper, more strenuous walks, I found it became clammy inside as the 2.5-layer construction lacks the next-to-skin comfort and moisture-wicking capability of a 3-layer jacket. It also lacks pit zips, a significant omission for active use. Despite this, for its intended purpose, a lightweight, packable, and reliable waterproof for general walking and as a ‘just-in-case’ shell, it offers unbeatable value.

Pros

• Genuine GORE-TEX waterproofing at a very accessible price point.
• Extremely lightweight and packable, perfect for stashing in a daypack.
• Fully adjustable hood provides good protection.
• Durable for its weight, suitable for year-round trail activities.
• Great value for money from a trusted UK brand.

Cons

• No pit zips, limiting ventilation during high-exertion activities.
• 2.5-layer construction can feel clammy and less breathable than 3-layer alternatives.
• Some users report the fit can be a little baggy.
• Not as robust as heavier jackets for scrambling or use with heavy packs.

Best for day hikers, dog walkers, and travellers looking for a lightweight, packable, and affordable GORE-TEX jacket for moderate UK conditions.Check Price on Amazon UK

Arc’teryx Beta LT: Best Premium Shell

UK Performance Testing

The Arc’teryx Beta LT is the benchmark against which all other serious mountain shells are measured. I reserved this jacket for the most demanding conditions: a winter ascent of Ben Nevis in driving snow and a multi-day wild camp in the Fisherfield Forest, known as ‘The Great Wilderness’. The performance is, simply, flawless. The 3-layer GORE-TEX (often the ‘Pro’ variant in higher-end models) is utterly impervious to weather. Wind, sleet, and torrential rain are shrugged off without a second thought. But its real magic is the combination of that protection with outstanding breathability. Even when working hard with a heavy pack, moisture management is superb, aided by well-placed pit zips. Every detail is perfected: the StormHood is the best in the business, cinching down perfectly over a helmet or bare head without restricting vision; the WaterTight™ zips glide smoothly; and the articulated ‘e3D’ patterning provides an unrivalled freedom of movement. Yes, the price is eye-watering, but for those who regularly venture into serious UK mountain environments, it’s an investment in safety, comfort, and gear that will last for years.

Pros

• Unbeatable weather protection from 3-layer GORE-TEX Pro fabric.
• Exceptional breathability for a hardshell, managing sweat during high-output activity.
• Best-in-class helmet-compatible StormHood offers superb protection and visibility.
• Impeccable build quality and attention to detail, from zips to seam taping.
• Lightweight (LT) for its level of durability and protection.
• Excellent articulation and fit for unrestricted movement.

Cons

• Extremely high price tag.
• ‘Trim’ fit may require sizing up for significant winter layering.
• Overkill for casual walking or low-level hikes.

Best for serious mountaineers, climbers, and dedicated winter hillwalkers who demand the absolute best in performance and are willing to invest in it.Check Price on Amazon UK

Alpkit Gravitas: Best UK Value

UK Performance Testing

Alpkit, a direct-to-consumer brand from the Peak District, has a reputation for creating high-performance gear at sensible prices, and the Gravitas is a prime example. At just 260g, this is a true ultralight jacket, but unlike many rivals, it uses a 3-layer construction. I tested this on a fast-packing trip along Hadrian’s Wall, where its minimal weight was a huge benefit. The jacket packs down to the size of an apple, disappearing into a running vest. Despite its featherlight feel, the 20k/20k waterproof and breathability ratings are solid. It held off several hours of persistent Northumberland rain, and its breathability was impressive, preventing that ‘boil-in-the-bag’ feeling on climbs. The hood, with its wired peak and simple rear adjustment, is surprisingly effective for such a light jacket, staying put in the wind. The trade-off is durability; the 10D face fabric feels delicate and wouldn’t be my first choice for tough scrambling or winter mountaineering. It also lacks pit zips. However, for the price, getting a 3-layer jacket this light with this level of performance is exceptional value.

Pros

• Incredibly lightweight (260g) and extremely packable.
• Excellent value, offering 3-layer performance at a 2.5-layer price.
• Great breathability (20k+ MVTR) for fast-paced activities.
• Well-designed hood with a wired peak and effective adjustment.
• Uses recycled face fabric and has a PFC-free DWR.

Cons

• Thin 10D face fabric is less durable and not ideal for abrasive use.
• No pit zips for extra ventilation.
• Minimalist design means only one chest pocket.
• Slim fit may require sizing up for layering.

Best for ultralight backpackers, trail runners shoes, and fast-and-light hikers who prioritise weight and packability and want incredible value for money. These options not only cater to those looking for lightweight solutions but also excel in comfort and durability for extended adventures.

Outdoor Research Foray: Best for Durability & Ventilation

UK Performance Testing

The Outdoor Research Foray has a legendary feature that makes it uniquely suited to the humid, damp conditions often found in the UK: the TorsoFlo™ vents. These are enormous zips running from the hem all the way to the bicep, allowing you to open the jacket up like a poncho while keeping your shoulders and back covered. I found this invaluable on a warm, wet hike up Moel Siabod in Snowdonia, where I could dump heat instantly without getting soaked. The jacket is built tough. The latest 3L AscentShell version (which replaces the older GORE-TEX model) uses a robust 40D recycled nylon face fabric that feels far more durable than lighter jackets. It shrugged off scrapes against rock and brambles without issue. While it’s one of the heavier jackets in this test at 420g, the weight is justified by its durability and unparalleled ventilation. The waterproofing is solid, and the AscentShell fabric offers excellent breathability. The fit is a little roomier, which is great for layering, but some might find it boxy.

Pros

• Unique and massive TorsoFlo™ vents offer unrivalled ventilation.
• Very durable and robust 3-layer construction (AscentShell version).
• Excellent weather protection, fully waterproof and windproof.
• Roomy fit is perfect for layering in cold UK winters.
• Well-featured with an adjustable hood and multiple pockets.

Cons

• Heavier and less packable than other jackets in the test.
• The fit can feel a bit boxy or baggy for slimmer builds.
• Hood adjustment can be finicky compared to premium rivals.

Best for hikers and backpackers who run hot or hike in humid conditions and need a durable, versatile jacket with the best ventilation on the market. Check Price on Amazon UK

Marmot Minimalist: Best Feature-Rich All-Rounder

UK Performance Testing

The Marmot Minimalist has been a stalwart of the UK hiking scene for years, hitting a sweet spot of performance, features, and price. I tested the GORE-TEX Paclite version on a coastal walk in Pembrokeshire, where it faced sea spray and sharp showers. The jacket feels more substantial than its ‘Minimalist’ name suggests. The face fabric is robust, and the GORE-TEX membrane provides reliable waterproofing. It’s packed with features you’d expect on a more expensive jacket: pit zips for ventilation, an excellent adjustable hood with a stiffened brim, and Velcro cuffs. The breathability is decent for a 2.5-layer jacket, though it can’t match 3-layer shells or the Foray’s massive vents during intense effort. The fit is a highlight; it’s comfortable and allows for layering without being overly baggy. While newer versions have transitioned to Pertex fabric, the GORE-TEX model remains a fantastic buy if you can find it. It’s a jacket that does everything well, making it a superb choice for those who want one jacket for everything from the daily commute to weekend mountain adventures.

Pros

• Proven GORE-TEX waterproofing in a well-priced package.
• Excellent feature set including pit zips, adjustable hood, and secure pockets.
• Durable and robust feel for a 2.5-layer jacket.
• Comfortable ‘Angel-Wing Movement’ fit allows for great mobility.
• Versatile design works well on the trail and around town.

Cons

• Breathability is only average and can feel clammy during hard exercise.
• Some users find the main zipper less robust than on premium jackets.
• Body length can be slightly short for taller users.

Best for the all-round outdoor enthusiast who wants a single, reliable, and feature-packed waterproof jacket for hiking, travel, and everyday use.Check Price on Amazon UK

Decathlon Forclaz Trek 500: Best on a Tight Budget

UK Performance Testing

For those entering the world of hiking or on a strict budget, the Decathlon Forclaz Trek 500 is hard to ignore. I tested this jacket on low-level woodland walks in the New Forest. It’s important to set expectations: its 10,000mm waterproof rating is significantly lower than the others on this list. It will keep you dry in showers and moderate rain, but I wouldn’t trust it for a full day in a mountain downpour. Many versions are sold as a ‘3-in-1’ system with a removable fleece or padded inner, which offers fantastic versatility and value for money, but compromises its performance as a dedicated hiking shell. The outer jacket on its own is reasonably light, but breathability (rated RET 12) is limited, and I found it got sweaty quite quickly on inclines. However, it often includes pit zips, which is a fantastic feature at this price. The build quality is surprisingly good, and it has plenty of pockets. It’s not a technical mountain jacket, but as a versatile piece for casual walking, travel, and surviving the British weather on a budget, it’s an excellent choice.

Pros

• Exceptional value for money.
• Often available as a versatile 3-in-1 system with a removable inner layer.
• Includes features like pit zips and multiple pockets, rare at this price.
• Decent durability for general use.

Cons

• A lower waterproof rating (10,000mm) is not suitable for prolonged heavy rain.
• Limited breathability can lead to sweat build-up.
• Bulkier and heavier than more technical jackets.
• Not designed for serious mountain conditions.

Best for beginners, casual walkers, or anyone on a tight budget needing a versatile jacket for light rain and general outdoor use.

4. Waterproof Technology Explained: Decoding the Jargon

Choosing a waterproof jacket can feel like deciphering a secret code. GORE-TEX, HH, MVTR, DWR… what does it all mean? Understanding these core technologies is the key to selecting a jacket that will actually keep you dry and comfortable in the uniquely damp and challenging UK climate.

Waterproof Ratings (Hydrostatic Head – HH)

This is the single most important number. Measured in millimetres (mm), the Hydrostatic Head (HH) rating tells you how much water pressure a fabric can withstand before it leaks. A 1-inch square tube is placed on the fabric and filled with water until it penetrates. The height of the water column in mm is the rating.

• 5,000mm: The minimum for a jacket to be called ‘waterproof’. Fine for a light shower or walking the dog, but will fail in sustained UK rain.
• 10,000mm – 15,000mm: A good starting point for hiking. Will handle most downpours but may struggle under pressure (e.g., from backpack straps) or in prolonged, driving rain.
• 20,000mm and above: The gold standard for UK mountain weather. This level of waterproofing will withstand heavy, persistent rain and the pressure exerted by rucksack straps, ensuring you stay dry in the worst conditions. All our top-rated jackets meet or exceed this standard.

Breathability Ratings (MVTR)

A jacket that doesn’t breathe is a glorified plastic bag. You’ll get soaked from your own sweat. Breathability is measured by the Moisture Vapour Transmission Rate (MVTR), in grams of water vapour that can pass through a square metre of fabric in 24 hours (g/m²/24h).

• <10,000g/m²: Suitable for low-intensity activities like city walking. You will get sweaty on a hill climb.
• 10,000 – 20,000g/m²: The sweet spot for most UK hiking. This offers a good balance, allowing sweat to escape during moderate exertion.
• 20,000g/m²+: Essential for high-output activities like fast hiking, scrambling, or mountaineering. This level of breathability actively works to keep you dry from the inside.

Waterproof Membranes: The Engine of Your Jacket

The magic happens in a microscopic layer called a membrane, which is laminated to the inside of the face fabric. This membrane has billions of pores per square inch, each one too small for a water droplet to pass through, but large enough for a water vapour (sweat) molecule to escape.

• GORE-TEX: The most famous brand. They offer several types:
  • GORE-TEX Performance/Standard: The versatile all-rounder, found in jackets like the Montane Phase. Often comes with a 28,000mm HH rating.
  • GORE-TEX Pro: The most rugged and durable option, designed for extreme conditions. Found in the Arc’teryx Beta LT, it offers maximum protection and excellent breathability.
  • GORE-TEX Paclite: A 2.5-layer system designed to be lightweight and packable, but less breathable and durable. Used in the Berghaus Paclite 2.0.
  • GORE-TEX C-Knit: A 3-layer fabric with a softer, more comfortable backer, improving next-to-skin feel.
• eVent: A major competitor to GORE-TEX, known for its exceptional ‘direct venting’ breathability. It doesn’t need a build-up of moisture to start working, but can require more frequent cleaning to maintain performance.
• Proprietary Membranes: Many brands develop their own excellent membranes. Rab’s Pertex Shield (used in the Downpour Plus 2.0) and Montane’s own fabrics offer performance that often rivals GORE-TEX at a lower price point. Patagonia’s H2No and The North Face’s FUTURELIGHT are other high-performing examples.

Durable Water Repellent (DWR)

DWR is a chemical coating applied to the outer fabric. It’s your jacket’s first line of defence, causing water to bead up and roll off. When it’s working, it prevents the face fabric from getting saturated (or ‘wetting out’), which is crucial for breathability. A wetted-out jacket can’t breathe, making you feel cold and clammy, even if the membrane hasn’t leaked. DWR is not permanent and needs regular cleaning and re-proofing.

5. How to Choose the Best Waterproof Jacket for UK Weather

The UK’s weather is a unique challenge: it’s not just about heavy rain, but also high humidity, strong winds, and rapid temperature changes. Choosing the right jacket means looking beyond the headline stats and focusing on features that work in our specific environment. After countless hours on windswept ridges and in damp valleys, here’s what I’ve learned is non-negotiable. A waterproof outer layer is essential, but so is a reliable insulation system underneath. Considering the upcoming trends, the best base layers for winter 2025 should prioritize moisture-wicking properties and warmth without bulk, allowing for comfortable layering in unpredictable conditions. Investing in these features can make all the difference when tackling the elements head-on.

Waterproof Rating: Aim for 20,000mm Minimum

While a 10,000mm jacket might suffice for a brief shower, the UK specialises in persistent, driving rain that can last for hours. More importantly, the pressure from your rucksack’s shoulder and hip straps can force water through lower-rated fabrics. For any serious hillwalking, especially in places like Snowdonia, the Lake District, or Scotland, a 20,000mm Hydrostatic Head (HH) rating is the baseline for reliable, all-day dryness. Anything less is a compromise that will likely leave you damp when you’re miles from shelter.

Breathability & Pit Zips: Your Secret Weapon Against Sweat

In the UK, you’re often climbing steep hills in cool, humid air. It’s the perfect recipe for sweating inside your “waterproof” jacket. This is where breathability becomes just as important as waterproofing. A jacket with a high MVTR rating (ideally 15,000g/m² or more) allows that sweat vapour to escape. However, no membrane can cope with the amount of sweat produced during a strenuous ascent. This is why pit zips (underarm ventilation zips) are an essential feature for UK hiking. They allow you to dump a huge amount of heat and moisture quickly without having to take your jacket off in the rain. Jackets like the Rab Downpour Plus 2.0 and Outdoor Research Foray excel here.

Hood Design: Your Shield Against Wind and Rain

A poorly designed hood is useless in the British wind. It will either blow off your head or obscure your vision. Look for a hood with:

• Three-point adjustment: Toggles at the sides to cinch around your face and one at the back to adjust volume. This creates a snug fit that moves with your head.
• Stiffened or wired peak: This is crucial. A stiff peak holds its shape in the wind and keeps rain from dripping directly onto your face and into your eyes.
• High collar: A collar that zips up to cover your chin and mouth provides vital protection from wind chill and driving rain.

The hood on the Arc’teryx Beta LT is the gold standard, but the Rab and Montane models also perform exceptionally well in this regard.

Weight vs. Durability: Finding the Right Balance

There’s a direct trade-off between how light a jacket is and how durable it is. Ultralight jackets (under 300g) like the Alpkit Gravitas are fantastic for fast-and-light adventures but use thinner face fabrics (e.g., 10-15 Denier) that are more susceptible to abrasion from rocks or heavy rucksacks. For general UK mountain use, a jacket in the 350g-450g range with a 30D or 40D face fabric (like the Montane Phase or OR Foray) offers a great balance of durability for regular use without being excessively heavy.

Packability: Be Ready for Anything

The one certainty of UK weather is its uncertainty. A day that starts with glorious sunshine can end in a hailstorm. Your waterproof jacket will spend a lot of time in your pack, so it needs to be reasonably packable. Most modern jackets will pack into their own pocket or a small stuff sack. While ultralight models are the most compact, even robust 3-layer jackets are far more packable than they used to be. Ensure your chosen jacket fits easily into your daypack with room for your other essentials.

Fit and Layering

Your waterproof jacket is the outer layer of a system. It needs to fit comfortably over a base layer and a mid-layer (like a fleece or insulated jacket) for cold conditions. Look for a ‘regular’ or ‘active’ fit that isn’t too baggy (which can catch the wind) but isn’t too tight to restrict movement or layering. Articulated sleeves (pre-shaped for a natural bend at the elbow) and a dropped rear hem (for extra coverage when bending over or wearing a pack) are signs of a well-designed hiking jacket.

6. Using & Caring for Your Jacket in UK Conditions

Investing in a quality waterproof jacket is the first step; knowing how to use and care for it is the second. Proper use and maintenance will not only keep you comfortable but will dramatically extend the life of your gear, especially in the damp and often muddy UK environment.

The Layering System: The Foundation of Comfort

Your waterproof jacket is a ‘shell’, the final piece of a three-part layering system designed to manage moisture and temperature.

• Base Layer: Worn next to the skin. Its job is to wick sweat away. Choose merino wool or synthetic fabrics. Never wear cotton, as it absorbs moisture and will make you cold.
• Mid-Layer: This is your insulation. A fleece jacket is a versatile and popular choice for UK hiking. In colder winter conditions, a synthetic or down insulated jacket can be used.
• Outer Shell: Your waterproof jacket. It protects you from wind and rain while allowing the moisture wicked by the other layers to escape.

By adding or removing the mid-layer and using your shell’s vents, you can adapt to any condition without having to stop and change completely.

Washing: Don’t Be Afraid to Clean Your Jacket

Dirt, mud, sweat, and body oils clog the pores of the waterproof membrane, destroying its breathability. A dirty jacket will make you feel clammy and wet from the inside.

• When: Wash your jacket every 10-20 uses, or whenever it looks visibly dirty or starts ‘wetting out’.
• How: Close all zips and Velcro tabs. Use a specialist technical wash like Nikwax Tech Wash or Grangers Performance Wash. Do NOT use standard laundry detergent or fabric softener, as they leave residues that impair performance. Wash on a gentle 30°C cycle.
• Drying: Tumble dry on a low heat for 20 minutes after it’s dry (if the care label allows). The heat is crucial as it reactivates the DWR coating. If you don’t have a tumble dryer, you can iron on a low setting with a towel between the iron and the jacket.

Re-proofing DWR: Bringing Back the Beads

The Durable Water Repellent (DWR) is the coating that makes water bead up and roll off. When it wears off, the outer fabric gets saturated, which kills breathability. You’ll know it’s time to re-proof when water no longer beads but soaks in, making the fabric look dark. After washing your jacket, apply a wash-in or spray-on proofer like Nikwax TX.Direct or Grangers Clothing Repel. Follow the product instructions, and always finish with the heat treatment (tumble dry or iron) to bond the DWR to the fabric.

Storage

Don’t store your jacket compressed in its stuff sack for long periods, as this can create permanent creases that damage the membrane. Once it’s clean and completely dry, hang it in a cool, dry wardrobe. This allows the fabric to rest and ensures it’s ready for your next adventure.

7. Where to Buy Waterproof Jackets in the UK

Finding the right jacket is one thing; knowing where to buy it is another. The UK has a fantastic range of specialist outdoor retailers, both online and on the high street, where you can find expert advice and a wide selection of brands. Here are some of the best places to shop for your next waterproof jacket.

Online Retailers

• Decathlon: The home of Forclaz and Quechua, Decathlon is the go-to for budget-friendly gear. You can only buy their jackets from their own stores or website.

When possible, we recommend trying a jacket on in-store to check the fit, especially how it works with the layers you already own and your rucksack. However, online retailers often provide the best prices, so a combination of high-street research and online purchasing can yield the best results.

8. Frequently Asked Questions (FAQs)

Q1: What waterproof rating (HH) do I really need for UK weather?

For serious UK hillwalking, aim for a minimum of 20,000mm. While 10,000mm can handle a shower, the UK’s persistent, wind-driven rain and the pressure from rucksack straps can overwhelm lower-rated jackets. A 20,000mm rating ensures you stay dry even in a day-long deluge in the Scottish Highlands.

Q2: Is GORE-TEX still the best waterproof fabric?

GORE-TEX is the most famous and offers a guaranteed standard of performance, especially their GORE-TEX Pro fabric. However, many brands now have proprietary fabrics like Rab’s Pertex Shield and Patagonia’s H2No that offer comparable waterproof and breathability ratings (e.g., 20k/20k) at a more competitive price. For most UK users, a high-spec proprietary fabric is more than good enough.

Q3: Why do I still feel wet inside my expensive waterproof jacket?

This is almost always due to sweat, not a leak. If your jacket’s breathability (MVTR rating) is too low for your activity level, or if the outer fabric has ‘wetted out’ (see Q5), your sweat vapour can’t escape. It condenses on the cool inner surface of the jacket, making you feel damp. This is why high breathability and pit zips are crucial.

Q4: Are pit zips really necessary?

For active use in the UK, yes. Our cool, humid climate means you can be sweating on a climb even when it’s raining. Pit zips are the most effective way to dump excess heat and moisture vapour quickly, dramatically improving your comfort and preventing you from getting soaked from the inside.

Q5: What does ‘wetting out’ mean and how do I stop it?

‘Wetting out’ is when the outer fabric of your jacket becomes saturated with water because the Durable Water Repellent (DWR) coating has worn off. The jacket is still waterproof (thanks to the membrane), but it can’t breathe. To fix it, you need to wash the jacket with a technical cleaner and reactivate the DWR with heat (a tumble dryer on low or a cool iron).

Q6: How often should I wash my waterproof jacket?

More often than you think! For regular use (e.g., every weekend), wash it every 4-6 weeks. For light use, twice a year is sufficient. Dirt and body oils clog the membrane and ruin breathability. Always use a technical wash like Nikwax Tech Wash, never standard detergent.

Q7: What’s the difference between a 2.5-layer and a 3-layer jacket?

A 3-layer jacket bonds the outer fabric, waterproof membrane, and an inner protective lining into one robust material. It’s more durable and breathable. A 2.5-layer jacket has the outer fabric and membrane, but replaces the inner lining with a thin printed or sprayed-on coating. This makes it lighter and more packable but less durable and can feel clammy against the skin.

Q8: Is a £500 jacket really better than a £150 one?

It depends. A £500 jacket like the Arc’teryx Beta LT uses more advanced materials (like GORE-TEX Pro), has a more refined fit, and superior construction, making it more durable and breathable under extreme conditions. However, a £150 jacket like the Rab Downpour Plus 2.0 offers fantastic 20k/20k performance that is more than adequate for 95% of UK hikers. The extra cost brings diminishing returns for most users.

Q9: How should a waterproof jacket fit?

It should be long enough to cover your lower back when you bend over and have sleeves that cover your wrists when you reach forward. It should have enough room to comfortably fit a base layer and a fleece or light insulated jacket underneath, but not be so baggy that it catches the wind.

Q10: What is the best way to layer under a waterproof jacket for UK weather?

Use a three-layer system: 1) A synthetic or merino wool base layer to wick sweat. 2) A fleece mid-layer to provide insulation. 3) Your waterproof outer shell to block wind and rain. Avoid cotton at all costs.

Q11: How long should a waterproof jacket last?

With proper care, a good quality jacket should last 5-10 years of regular use. The waterproof membrane itself is very durable. The first thing to fail is usually the DWR coating (which can be reapplied) or the seam tape (which can sometimes be repaired). Cheaper jackets may only last 2-3 years.

Q12: Can I repair a tear in my waterproof jacket?

Yes. For small nicks and tears, you can use specialist waterproof repair tape (like GORE-TEX patches or Tenacious Tape) to create a durable, waterproof seal at home. For more significant damage, brands like Rab and Berghaus offer professional repair services.

Q13: What’s more important, waterproofness or breathability?

They are equally important. A jacket that isn’t waterproof is useless in the rain. A jacket that isn’t breathable will get you soaked with sweat from the inside. For the UK, you need a jacket that excels at both.

Q14: Are insulated waterproof jackets a good idea for UK hiking?

Generally, no. 3-in-1 or insulated waterproof jackets are too warm and not breathable enough for active hiking. You’ll overheat quickly. It’s far more versatile to use a separate insulation layer (like a fleece) and a waterproof shell, allowing you to adapt to changing conditions.

Q15: What does ‘fully taped seams’ mean?

When a jacket is sewn, the needle holes create potential leak points. ‘Fully taped seams’ means that every single seam on the inside of the jacket has been sealed with waterproof tape. This is an essential feature for a truly waterproof garment.

Q16: Do I need waterproof trousers as well?

For any serious hillwalking in the UK, yes. In heavy rain, water will run off your jacket and soak your trousers, leading to cold and discomfort. A pair of lightweight, packable waterproof overtrousers is an essential part of your kit.

Q17: What is a PFC-free DWR?

PFCs (Per- and Poly-fluorinated Chemicals) are traditionally used in DWR coatings but are harmful to the environment. Many brands are now switching to more environmentally friendly PFC-free alternatives. These may require slightly more frequent re-proofing but are a much more sustainable choice.

Q18: How should I store my jacket?

After use, make sure it is completely dry. Then, hang it in a cool, dry place. Avoid storing it compressed in its stuff sack for long periods, as this can damage the waterproof membrane over time.
