Submerging your body into freezing cold water, be it a lake, ocean or plunge pool, may not seem like the most appealing prospect, but fans of wild swimming, or open water swimming, swear by its invigorating, mood-boosting health benefits.
Over the past few years, swathes of people – wrapped in changing robes and armed with flasks of hot tea – have taken to the waters to reap the physical and psychological rewards of the toe-numbing practice – even in the winter months.
Tempted to take the plunge? We roped in the experts, along with a group of wild swimmers, to provide some tips to get started and help you choose the right cold water swimming gear to invest in. Let’s dive in, shall we?
How we test cold water swimming gear
We recruited a panel of keen cold plungers to brave the waves and help us find the best wild swimming gear – including swimsuits, wetsuits, changing robes, rash vests, dry bags and goggles – to suit all needs.
Our panel put the kit through its paces during a series of swims in lakes, rivers and the sea before reporting back on how they found each item’s design, fit, comfort and, most importantly, performance.
Our top performers kept the cold water at bay, provided unparalleled warmth and allowed our testers to stay comfortable in chilly water, even for extended periods. They were easy to get on and off and scored highly for flexibility and buoyancy, where relevant. Bonus points were awarded for attractive designs.
Back in the Good Housekeeping Institute lab, our experts collated all the feedback, and overall scores were awarded.
The best cold water swimming gear for 2025
The best cold water swimsuits
These are an obvious essential – unless you want to skinny dip! You can, of course, swim in anything you have in the cupboard, but it’s worth investing in a swimsuit that’s specifically designed for wild swimming. We recommend choosing one with an active fit and plenty of flexibility. Comfort is also key.
Long-sleeved suits offer extra protection from the elements, zipped designs allow for easy on-off and UV protection is handy for the summer months.
Score: 98/100
Testers raved about the soft, flexible fabric and sleeveless design, which allowed for total freedom of movement. “It felt like a second skin,” one tester told us, adding that they barely noticed they had it on. It will keep you warm in chilly waters, yet it’s still thin enough to wear underneath a wetsuit if you want extra coverage.
Score: 91/100
This impressed our testers on all fronts, including style, comfort and performance. It comes in a range of patterns and will keep you visible when you’re in the water. Thanks to the long sleeves and high neckline, it’s a good one to go for if you’re swimming for lengthier periods or if it’s particularly cold outside.
Score: 80/100
Testers loved the "high-quality", "luxurious" design with smooth front zip and comfortable, chafe-free fabric. Even those with larger breasts found it provided sufficient support in the water. It has built-in UV50+ sun protection and is resistant to chlorine. Note, the cutaway in the back does leave you exposed to cold water.

The best changing robes
A good changing robe can make the difference between skipping your swim on cold, grey days, and going for it, knowing you’ll warm up quickly post-dip. Also, with no changing rooms outdoors, it can be difficult to protect your modesty, which is where a changing robe comes into its own.
Opt for a robe that’s made with quick-drying, absorbent materials and is roomy enough for you to discard your swimwear discreetly. A hood will help you retain warmth and stay cosy, while internal storage pockets are handy for stashing your essentials including underwear and valuables.
Score: 90/100
This came out on top for warmth and comfort. It features a fast-drying, moisture-absorbent lining, zipped pockets for your phone and purse, plus plenty of deep fleecy pockets to warm hands. There are hooks on the zips so you can open and close the pockets easily and two-way reversible zips to make the changing process easier.
Score: 87/100
This unisex robe – which features a peaked hood, adjustable cuffs and a Sherpa lining – kept testers cosy and dry in wet, windy conditions. There are zipped pockets for your valuables, fleecy, hand-warmer pockets and a large internal drop pocket. It even packs down to a tow float to keep you visible during open-water activities.
Score: 83/100
Want something that will protect you from the elements but won’t trail along the floor behind you? This mid-length robe is perfect. It has a drawstring hood and is made from water-resistant fabric, so it will protect against wind chill and light rain. The inner lining is breathable and and there are generous pockets.

The best wetsuits
Wetsuits are optional. Many outdoor swimmers prefer the more natural feeling of just being in a swimsuit, even in cooler temperatures, but if you like the idea of some insulation or you’re planning to do longer swims in chilly water, a wetsuit will help your body retain warmth. It will also increase your buoyancy, making swimming feel that bit easier.
Score: 97/100
This technical suit is made from super stretchy, biodegradable neoprene fabric. According to testers, it’s quick and simple to put on and take off solo and they enjoyed plenty of flexibility around the chest and shoulders. They felt speedy and streamlined in the water and it kept them warm on chillier dips.
Score: 94/100
Looking to invest in a durable, high-performing option that will keep you ultra cosy in the cold water? Meet your perfect match. This neoprene number was a hit with our panel. They raved about the "excellent quality" fabric and liked that it comes with gloves, so you don't have to worry about snagging the material as you slip it on.
Score: 80/100
This 2.5mm thick neoprene suit is ideal for the warmer months. Not only do the colourful arms look good, but they also add an element of safety due to increased visibility when you're in the water. Testers said the suit was comfortable to swim in and it didn't restrict movement around the arms. A great value pick.

The best rash vests
If you want some extra protection in the water but don’t fancy a full wetsuit, a rash vest is a good middle ground. It provides warmth, buoyancy, and protection from UV rays and abrasions. Plus, it can help take the initial shock of cold-water swimming away.
When choosing a rash vest, a snug fit is recommended, with a thickness of around 2-3mm for warmth without sacrificing flexibility. Additional features such as high collars and zips are also worth considering.
Score: 86/100
A top-quality rash vest doesn't have to cost over the odds, as this short-sleeved gem proves. The fabric was extremely lightweight and stretchy and allowed for speedy changing. It didn’t cause any rubbing or chafing and it has top level UPF 50+ UV protection.
Score: 86/100
This high-neck, short-sleeved style from the experts at Orca can be worn underneath a wetsuit or on its own for an added layer of warmth or some extra coverage over your swimsuit. Our testers praised the comfy fabric (which comes with built-in sun protection) and slim-fit design.
Score: 83/100
Let’s state the obvious: this rash vest looks great, and everyone will envy you. Sure enough, testers thought it was “super stylish” and said they felt “very confident” when wearing it. Performance-wise, it exceeded our panel’s expectations. with the full-coverage design keeping them cosy as they plunged into cold water.
The best dry bags
A dry bag does exactly what it says on the tin – it keeps your belongings dry in wet environments. They come in various sizes and are made from durable, waterproof materials with a roll-top closure that seals the bag tightly. Many also feature straps or handles for portability and to let you securely attach them to your other gear.
They’re ideal for storing items including clothes, electronics and food, protecting them from water exposure during outdoor activities.
Score: 76/100
This is a simple, fuss-free design at an affordable price. The 25L bag is made from durable nylon PVC and can fit all your essentials. It’s lightweight and flexible and though it doesn’t come with a carry strap, there are clips so you can attach it to your rucksack.
Note, the brand says it won’t provide watertight protection when completely submerged in water.
Score: 75/100
This dinky 10L dry bag is great for taking your phone, keys, wallet and other essentials. You could fit a swimsuit and wetsuit in there, but it would be a squeeze. It features splashes of bright orange to aid visibility, a handle at the bottom so you can hang it upside down when it’s drying and a multi-way shoulder strap.
Score: 75/100
This roomy 40L dry bag will fit a swimming costume, wetsuit and even a dry robe. Testers said the adjustable rucksack-style straps and handle at the top made it easy to carry and they found the double PVC-laminated polyester “robust and durable”. The roll top bag is splash-proof when closed properly, but the brand doesn’t recommend submerging it in water.
The best open water swimming goggles
If you want to swim with your head under the water, goggles can improve your vision and enhance your performance, especially if you're swimming long distances. Wide lenses will serve you well in open water, as it’s easier to see what’s going on around you. A pair with tinted, mirrored or polarised lenses can also help reduce glare, while built-in UV protection will protect your eyes from the sun.
Score: 94/100
Zone3’s goggles have wide lenses, offering excellent peripheral vision in the water. These earned brownie points for adjustability – testers said it was a doddle to adjust the strap and there’s a replaceable nose bridge for the perfect fit. We recommend opting for the polarised lenses to filter glare when swimming outside.
Score: 94/100
With wide lenses for better peripheral vision and built-in anti-fog technology, these Orca goggles are great for wild swims. Our panellists said the visibility was excellent, even over long distances, and they formed a good seal around the eyes. They also left faces free from goggle marks and come with a case.
Score: 88/100
We rated Speedo’s original Biofuse goggles (they also scored 88/100 in our tests) and the 2.0 version is just as impressive. Designed for female faces, they feature wide lenses and boast a shiny new push button, making it a cinch to adjust the strap. Other features include anti-fog protection and built-in UV protection.

What is cold water swimming?
Cold water swimming refers to taking a dip or swimming – in a costume or wetsuit – in any water that’s below 15C, explains cold water swim coach Gilly McArthur.The term is often used interchangeably with wild swimming and open water swimming, which take place in natural bodies of water such as ponds, lakes, rivers and oceans, rather than in a pool or lido.
What are the benefits of cold water swimming?
There’s a whole range of health benefits associated with swimming outdoors. Here are just some of them.
It’s a great form of exercise: Swimming is an excellent, low-impact way to move your body and work on your cardiovascular fitness. It can also help improve muscle tone and strength and targets the whole body.
It aids muscle recovery: Hollie Grant, ambassador for UK triathlon brand ZONE3, notes that swimming in cold water can help enhance circulation and blood flow, reduce inflammation and improve muscle recovery. Evidence backs this up, with studies revealing that it can help reduce DOMS (delayed onset muscles soreness), reduce swelling and shift lactic acid.
It’s a mood booster: Fitness aside, cold water swimming can have a major impact on your mood and overall mental health, helping to ease symptoms of anxiety and depression, says McArthur.
For her, one of its biggest draws is soaking up the natural light and being close to nature. “There’s growing evidence to show that access to green and blue spaces is linked to better health and improved wellbeing,” she says.
“We’re so connected to our screens and are lives are so busy, using this time to connect to yourself, your breath and mother nature can be superbly uplifting.”
Cold water instructor Lindsay Aubrey agrees, adding that after the initial shock, cold plunging activates your body’s relaxation response and makes you feel calm and tranquil. “It gives you a rush of endorphins that leaves you feeling energised and ready to seize day the day with positivity,” she says.
The social aspect: For many, the sense of community is a huge part of the attraction. “There’s an incredible sense of community among cold water swimmers. Nothing bonds people quite like facing a challenge and sharing the experience together,” says Aubrey.
What are the risks of cold water swimming?
Despite the myriad benefits, wild swimming doesn’t come without its risks, including cold shock response and hypothermia. You should be particularly careful if you are taking a dip in the chillier months.
“Cold water swimming can raise your blood pressure and isn’t suitable for everyone," warns McArthur. “It’s important to check with your doctor before getting started if you have any concerns at all.”
She adds that it’s important to learn how to swim safely in cold water – as with any outdoor activity, it can be dangerous if undertaken incorrectly.
It's advisable to enter the water slowly, without jumping in or submerging your head underwater until you’ve regulated your breathing. You should be aware of entry and exit points in the water and check the weather forecasts, tides and currents to ensure it’s safe to get in.
It’s also a good idea to wear something bright so you’re visible in the water, and swim with a friend or a group so if you do experience any issues, you aren’t alone.
How to get started with wild swimming
Ease yourself in: Ready to take the plunge? If you’re new to cold swimming, start slowly and build up your stamina over time. “You don’t need to stay in for ages – even just a few minutes in the water can boost your wellbeing,” says McArthur.
It’s also a good idea to start in the warmer months so your body can acclimatise to the chilly temps.
Do your research: Start by looking up local swimming spots. There are plenty of useful resources available online, including the Outdoor Swimming Society, Salty Sea Sisters and Swim England Open Water.
Don’t go it alone: Find some friends or join a local swimming group. Safety reasons aside, you and your pals can encourage and motivate each other, making you more likely to stick at it.
You could also join a beginner’s course or enlist the help of a cold-water swim coach to help you at the start of your journey and build some confidence.
Choose the right kit: Panic not – you don’t need to splash out on lots of pricey kit before diving in. “You only really need a swimsuit or a wetsuit if you want to wear one,” says McArthur.
If you do want to invest in the extras, a changing robe can help you dry off and get changed quickly, goggles are handy if you want to swim with your head under the water and a dry bag can be handy for storing your valuables. As with any kit, it comes down to personal preference – it's about finding what works for you and allows you to have a comfortable wild swimming experience.
