How to choose a waterproof jacket that won't let you down in 2026

Not all waterproof jackets are created equal, according to Which? members in our latest survey. Some jackets won't necessarily shelter you from the wind, keep you dry in the drizzle or stop you getting clammy on long hikes.

You’ll need to ensure that the waterproof jacket you choose has all the necessary technical specifications to keep you dry in the conditions you’re expecting, whether that’s autumn dog walks in the rain, or more severe conditions as the weather turns wintry.

Features that enable air to enter the jacket, such as vents and adjustable cuffs, can improve its breathability and comfort, while taped seams will prevent water from seeping in. Pick the right combination of features from a top-rated brand and you’re likely to feel much more prepared for whatever weather the end of the year brings.

So whether you’re investing in new gear for your next adventure or you’re looking for a gift for an outdoorsy loved one, read on to find the best jacket possible for the job.

Look at the waterproof jacket rating – and check the seams

When buying a jacket, check the tags or online description for the waterproof rating, known as the hydrostatic head. It’s measured in millimetres – and the higher the number, the better – but a 5,000mm minimum is recommended. 

You should also opt for something with taped and sealed seams. This prevents water from getting in through any holes created during manufacturing. If you can see the seams, it won’t be waterproof.

A jacket with storm flaps (a panel of fabric that covers the jacket's zips) will also help to keep you dry by preventing water from entering the coat via zip openings.

Go for a close fit – but not too close

Choosing a relatively close-fitting jacket means it won’t flap in the wind. But check that it's roomy enough to allow you to move freely and wear a jumper or winter top beneath. Test it by moving your arms in circles to see if your range of motion feels inhibited. If it does, try a larger size, or a different fit of jacket.

You should also lift both arms above your head to check the jacket still covers your lower back in this position — the right-sized waterproof should be long enough to still keep the rain out.

A drop tail (where the back of the jacket is longer than the front) is particularly useful. This feature gives you more coverage when bending forward and is particularly handy for cyclists.

Not all waterproofs do their job as well as others. See how different brands measured up against each other in our waterproof jackets survey. 

Check waterproof jackets for adjustability

Decent walking jackets will have drawstring hoods and hems – and often drawstring waistlines too – which means they fit more snugly and improve insulation. They will also protect you from wind and rain. Just check where the toggles will rest against your body, as they could dig in and prove uncomfortable during a long walk. 

An adjustable hem and waistline lets you use the waterproof jacket's toggles to tighten the coat to improve fit and aid insulation. 

Lastly, Velcro cuffs can help to keep out water and allow for ventilation in dryer conditions.

Inspect the hood on your waterproof 

A well-fitted hood should protect your face from the elements without restricting your view. A stiffened peak, with reinforced material and sometimes even inbuilt ‘brim wires’, help to prevent the hood from bending in the wind and direct the rain away from your face. You should be able to adjust the hood easily, even when wearing gloves.

Fixed hoods will prevent water from running down your neck and back, as will detachable hoods with a good overlap between the hood and collar. 

Look for a waterproof jacket with breathability technology

If you’re going to be out on walks and hikes when wearing your jacket, breathability is vital.

Select one with a membrane (Gore-Tex is the best known). This inner layer stops rain droplets from entering but allows sweat and heat to escape. 

Cheaper jackets tend only to have a water-repellent coating, so the trade-off is that they are less breathable. While that’s suitable for wearing around town, perhaps doing some shopping in the rain, it will fall short on a rainy winter hike in the Lake District. 

An added bonus is underarm ventilation (known as pit zips). As the name suggests, these can be zipped open to allow out trapped heat.

But beware that wearing a rucksack can make it tricky to access these zips and even distort the shape of the zip, increasing the chances of water entering. Ideally, take your rucksack along to the shop to try it on with the jacket.

Choose a jacket with good pocket accessibility

First, check there are enough pockets for your requirements, and make sure they’re big and deep enough for you.

You may need just one pocket for your phone and keys to walk the dog around the block. Serious hikers, however, might need pockets large enough to carry an OS map, and extra inside pockets to keep valuables dry in the rain or snow.

Trying your jacket on with a rucksack will also show you the pull it will have on the pocket positioning. Plus, take a pair of gloves to see how easy it is to open the jacket's pockets while wearing them.

Check how environmentally conscious the waterproof jacket brand is

PFAS (or PFCs) are synthetic chemicals traditionally used to make products waterproof – a job they do well. But they impact the planet by taking up to 1,000 years to decompose. It's worth looking out for PFC-free products.

Paramo, the best-rated brand in our waterproof jackets survey, guarantees all its products are PFC-free.
