Rain 🌧️ or shine ☀️, the British outdoors never fails to surprise us. One moment you’re admiring sun-dappled hills, the next you’re scrambling for cover as the skies open up. If you love walking, hiking, or exploring the wild corners of the UK (or beyond), you know that a trustworthy waterproof jacket isn’t just a nice-to-have; it’s essential kit.
But with so many jackets on the market, each promising cutting-edge technology and all-weather protection, how do you know which one is right for you? Should you go for GORE-TEX or try something new like Futurelight or Pertex Shield? What do all those numbers and layers actually mean? And how do you make sure your investment lasts season after season?
What Makes a Jacket Waterproof?
Hydrostatic Head: What Does It Mean?
When you see a jacket described as “waterproof,” it is not just marketing speak. The science behind it is called hydrostatic head, or HH. This measurement tells you how much water pressure a fabric can withstand before it starts to leak. In simple terms, the higher the number, the more rain the jacket can cope with before water begins to pass through.
A rating between 1,500 and 5,000mm is generally good for light showers and everyday use. If you spend more time hiking, backpacking, or dealing with heavy rain, 10,000 to 20,000mm is usually the safer range. For serious mountain adventures and extreme weather, 20,000mm+ gives you a stronger level of protection.
Tip: If you are regularly out in the hills or mountains, aim for at least 10,000mm. For everyday use, you may not need such a high rating.
Why Breathability Matters
Staying dry is not only about keeping rain out but also about letting sweat escape. If your jacket traps moisture inside, you can end up soaked from your own perspiration, which is why breathability matters just as much as waterproofing.
Breathability is measured by Moisture Vapour Transmission Rate, or MVTR. The higher the MVTR, the more vapour can move out through the fabric over a set time. In practical terms, lower numbers are fine for short walks or low-intensity use, while higher numbers are better if you are working hard, climbing hills, or moving quickly.
For extra ventilation, look for features such as underarm zips, often called pit zips. These can make a big difference when your body starts to warm up, and you want to dump heat fast without taking the jacket off.
- <10,000g/m²: Best for low-intensity activities or short walks.
- 10,000–20,000g/m²: Good for hiking, cycling, and general outdoor use.
- 20,000g/m²+: Ideal for high-output activities like running, fast hiking, or mountain sports.
Understanding Layer Constructions
One of the easiest ways to compare waterproof jackets is by looking at the layer construction. This tells you a lot about comfort, durability, and performance.
For everyday use, travel, or gentle walks, a 2-layer jacket offers comfort and affordability. It is a practical choice for people who want reliable protection without going too technical or too expensive.
A 2-layer jacket has a waterproof membrane bonded to the outer face fabric, with a lining inside to protect the membrane and improve comfort. That makes it feel soft and approachable, which is one reason it works well for commuters, dog walkers, and casual outdoor users. The trade-off is that it can feel a bit heavier and less breathable than more advanced options, so it is not always the best fit for high-exertion activity or harsh weather.
What to look for:
- Comfortable, slightly relaxed fit to allow for layering.
- Adjustable hood with a stiffened peak for visibility.
- Pockets placed above the hip belt for easy access when wearing a rucksack.
- A hem and cuffs you can cinch tight against the wind.
If speed and packability are top priorities, a 2.5-layer jacket is the agile choice. It is designed to keep weight down while still giving you the waterproof protection you need when the weather changes quickly.
A 2.5-layer jacket uses an outer face fabric, a waterproof membrane, and a thin inner protective layer instead of a full lining. That makes it exceptionally lightweight and easy to stow, which is why it is popular with fast hikers, runners, trail runners, cyclists, and lightweight adventurers. The downside is that this thin internal layer can feel a little clammy against bare skin, and the construction is usually less durable than a 3-layer jacket over time.
What to look for:
- Ultralight design, ideally under 300g if possible.
- Packability, so it fits easily into a running vest or small pack.
- Good ventilation, such as pit zips or mesh-lined pockets.
- Minimalist features to keep the weight down.
For harsh conditions or demanding mountain environments, a rugged 3-layer jacket stands out. It is built for people who need dependable protection, strong durability, and better long-term performance.
A 3-layer jacket has a tough outer shell, a waterproof and breathable membrane in the middle, and a protective inner lining, all bonded together into a single fabric. That construction gives it excellent abrasion resistance and strong weather performance, which is why serious hikers, climbers, and outdoor professionals often choose it. The trade-off is a higher price and a little more weight, but for frequent use in tough conditions, that is often a worthwhile compromise.
What to look for:
- 3-layer construction for maximum durability and weather protection.
- Reinforced shoulders and elbows to withstand abrasion from packs and gear.
- Helmet-compatible hood with multiple adjustment points.
- Snow skirt and storm flaps for extra protection.
Waterproof vs Water-Resistant: Don’t Get Caught Out
Waterproof jackets use membranes, coatings, and sealed seams to keep out heavy rain. They are built to handle proper weather, not just a passing shower.
Water-resistant jackets are different. They usually have a durable water repellent finish (DWR), but they will not stand up to prolonged downpours. They are fine for drizzle or brief spells of bad weather, but if you are heading out for a serious day in wet conditions, waterproof is the safer option.
A quick check can help here: if a jacket has taped seams and a hydrostatic head rating, it is waterproof. If it does not, it is more likely to be water-resistant rather than fully waterproof.

Features That Matter
A good hood can make the difference between a jacket that feels protective and one that feels awkward in wind and rain. It should tighten securely around your face, move with you, and give solid coverage without blocking your view.
Adjustability is the most important thing to look for. A stiffened peak helps stop rain from dripping into your eyes, while helmet compatibility is essential for climbers, skiers, and mountaineers. If you are using the jacket in rough weather, a well-designed hood can make a huge difference to comfort and confidence.
- Adjustability: Make sure the hood can be tightened around your face to keep out wind and rain.
- Stiffened peak: Stops rain from dripping into your eyes and improves visibility.
- Helmet compatibility: Essential for climbers, skiers, and mountaineers.
A waterproof jacket is only as good as its weakest point, and zips and seams are two of the most important areas to get right. Waterproof zips help stop rain getting in through the front opening, while storm flaps add an extra layer of protection over the zip.
Taped seams are a must for true waterproofing because they stop water sneaking through the stitch holes. Pit zips can also be very useful when you are working hard, because they let you release heat quickly without removing the jacket. These features may seem small, but they make a major difference once the weather turns and you need the shell to do its job properly.
- Waterproof zips: Look for brands like YKK Aquaguard or Vislon.
- Storm flaps: Extra fabric over the zip for added protection.
- Taped seams: A must for true waterproofing; stops water sneaking through stitch holes.
- Pit zips: Underarm zips for extra airflow on the move.
Pocket layout matters more than many people expect. If you are wearing a rucksack or harness, badly placed pockets can become awkward or unusable very quickly.
Chest pockets are often the most practical because they are easier to reach when a hip belt is in the way. Hand pockets are great for warming cold hands or stashing snacks, while internal pockets are useful for valuables such as a phone, map, or keys. The best pocket setup is the one that works with how you actually move outdoors, not just how the jacket looks on the hanger.
- Chest pockets: Easy to access with a rucksack or harness.
- Hand pockets: Great for warming hands or stashing snacks.
- Internal pockets: For valuables like your phone or map.
The cuffs and hem help seal the jacket against wind and rain, which is why they are worth paying attention to. A jacket that fits well around these areas feels more secure, more protective, and less likely to let weather creep in.
Hem drawcords help close off the bottom of the jacket, while adjustable cuffs let you fit the sleeves over gloves and stop water from running up your arms. These are the kinds of finishing touches that make a waterproof feel properly finished rather than just functional.
- Hem drawcords: Seal out wind and rain.
- Adjustable cuffs: Fit over gloves and stop water running up your sleeves.
Caring For Your Waterproof
How to Wash and Reproof
A good waterproof jacket should last for years if you look after it properly. Dirt, mud, sweat, and detergent residue can all reduce performance over time, so regular care is essential.
- Brush off dirt and mud.
- Use a specialist cleaner, like Nikwax Tech Wash or Grangers Performance Wash. Ordinary detergents can damage the membrane.
- Rinse thoroughly. Residue can affect waterproofing.
- Reproof with a spray or wash-in product when water stops beading on the surface.
- Dry properly: some jackets benefit from a gentle tumble dry to reactivate the DWR coating. Check the care label.
Small Repairs
Even a well-made waterproof can eventually pick up wear and tear. Small repairs are worth dealing with quickly, because minor damage can turn into a much bigger problem if it is left alone.
Tears and holes can often be fixed with repair tape, while leaky seams may need resealing with a seam repair product. These simple fixes can extend the life of your jacket and keep it performing well for longer, especially if you use it regularly in rough conditions.
Waterproof Technologies
Different brands use different waterproof technologies, and while the names may sound complicated, the aim is usually the same: keep rain out, let sweat escape, and do it in a way that suits the activity. The right technology for you depends on whether you want maximum all-round reliability, lightweight packability, or better airflow for high-output movement.
GORE-TEX is the best-known waterproof-breathable membrane and is widely used across outdoor clothing because of its strong reputation for dependable performance. It is designed to offer a reliable balance of waterproofing, breathability, and durability, which is why it is often found in jackets made for hiking, mountaineering, and all-round mountain use. Different versions of GORE-TEX are used in different garments, but the overall idea is the same: keep the weather out while helping moisture move away from the body. Shop GORE-TEX Jackets.
FutureLight, used by The North Face, is designed with breathability very much in mind. It uses a more advanced construction aimed at improving airflow while still maintaining waterproof protection, which makes it appealing for active users who are working hard and generating more heat. If you want a jacket that feels responsive during movement and does not overheat as easily, this is one of the technologies to look at. Shop The North Face Waterproof Jackets.
Pertex Shield is another lightweight waterproof option, and it is often chosen by brands such as Rab and Montane. It is known for being packable, breathable, and practical for fast-moving outdoor activity, where keeping weight down matters just as much as staying dry. It is a popular choice for trail running, fast hiking, and ultralight adventures because it gives solid protection without feeling overly bulky.
DryVent, also used by The North Face, combines a polyurethane coating with a durable water-repellent finish. It is often used in jackets designed for hiking, skiing, and general outdoor use, where dependable weather protection is more important than highly specialised technical performance. It tends to be a good all-round option for people who want a straightforward waterproof that handles everyday outdoor conditions well.
FAQs
Absolutely-just make sure it’s got a helmet-compatible hood and enough room for layers.
If you want versatility, yes. You get a waterproof shell and a detachable fleece or insulated liner-wear them together or separately.
Check for a hydrostatic head rating (ideally 1,500mm or higher), taped seams, and a description of the waterproof technology used. Membrane-based jackets and those with DWR (durable water repellent) coatings are best for heavy rain.
Yes, the DWR coating can wear off with use, dirt, and washing. Regular cleaning and reproofing help maintain performance. If water stops beading on the surface, it’s time to reproof.
Wash your jacket when it’s visibly dirty or if water stops beading on the surface-usually every few weeks if used regularly. Over-washing isn’t necessary and can reduce the lifespan of the DWR coating.
Look for an adjustable hood, taped seams, waterproof zips, ventilation (like pit zips), and pockets that are accessible while wearing a backpack.
Not necessarily. Lightweight jackets, especially those with modern membranes, can be highly waterproof. However, heavier jackets often offer greater durability and are better suited to harsh conditions.
Most modern waterproof jackets are designed to be breathable, but the level of breathability can vary depending on the fabric and technology used. Membrane jackets are generally more breathable than coated ones.
Look for a lightweight, highly breathable jacket with good ventilation. 2.5-layer membrane jackets are often ideal for running and fast hiking.
