Best wetsuits 2021: stay warm and protected in any season

We rank the best wetsuits around, whether you're surfing, paddle boarding, or trying a bit of wild swimming

One of today's best wetsuits is a must if you're planning on enjoying the waves for any length of time. Even in the summer, the seas (in the UK at least!) can get chilly very quickly, and donning a decent wettie will ensure you'll be able to wait for that perfect set for longer, or get a full hour underwater in warmth and comfort.

Wetsuit technology is on a steep upward curve, and improving every year. Today's best wetsuits today are increasingly environmentally savvy, as well as being ultra-plush and easier to don and doff – the latter vital when hopping round a National Trust car park trying to change. In this article, we've rounded up our pick of the best wetsuits to ensure you stay warm and protected, whatever the water's doing. 

In the UK, for summer use, a 3/2mm wetsuit will do the trick, though if you really feel the cold, you might prefer to play it safe with a 4/3 – which will have the added advantage of being warm enough for extended use from spring through to the autumn months. If you're planning to make the most of (relatively) crowd-free winter conditions, a 5/4mm wetsuit is an extremely wise investment, though you'll also need boots, a hood and gloves too.

Like most things in life, cheap wetsuits are usually to be avoided if you can help it as they will have a shorter lifespan, won't keep you as warm and tend to be much more restrictive. For a summer 3/2, it's worth spending around £200, while a decent winter 5/4 suit will be more like £250 to £300. Need more guidance? Head to the bottom of this article for our wetsuit buying advice.

For those planning a trip to the coast, there are a host of fantastic British locations for some serious surf action whether you're catching waves on a bodyboard, surfboard or stand-up paddle board (see our guide to the best paddle boards for beginners to get started) – or even embracing the majorly popular wild swimming trend. When packing for your trip, you might also want to invest in one of the best dry bags to stash your valuables in, and perhaps one of the best action cameras to capture your successes. 

The best wetsuits to buy now

O'Neill Hyperfreak wetsuit

(Image credit: O'Neill)

Best wetsuit overall

Material: Technobutter 3X neoprene
Seams: glued and blindstitched
Thickness: 2, 3/2, 4/3, 5/4+mm
Entry: chest zip
Main use: surfing
Reasons to buy
+Unparalleled flexibility+Fantastically warm and comfortable+Super quick drying
Reasons to avoid
-Easier to damage

When they launched in 2014, O'Neill's Hyperfreak wetsuits quickly gained a reputation for unparalleled levels of flexibility and warmth, but a life-span that was much shorter than conventional wetsuits. Fast forward to 2021 and the Hyperfreak range has evolved to become more flexible than ever, but is now much more resilient than earlier iterations. For that reason, this high-performing suit is our pick for best wetsuit overall right now. 

While a super-snug fit is vital if your wetsuit is to do its job correctly, it can feel restrictive if the neoprene prevents natural movements. O'Neill's Technobutter 3X branded neoprene has an amazing amount of four-way stretch that even in the thickest varieties enables free body movement and does not hamper paddling, pop-ups or any movements you make on the wave. It's also relatively soft to the touch and far easiest to get on and off than most front-zip wetsuits. Despite being much more robust than it used to be, Technobutter is still easier to damage that conventional neoprene, so take extra care when putting on and removing the wetsuit. Head to our O'Neill Hyperfreak review to find out more.

Rip Curl Flashbomb 3/2 Chest Zip wetsuit

2. Rip Curl Flashbomb 3/2 Chest Zip

Another excellent, flexible wetsuit

Material: neoprene
Seams: glued & blind stitched
Thickness: 3mm chest/2mm arms and legs
Entry: front chest zip
Main use: surfing
Reasons to buy
+Lightweight+Warm+Super stretchy
Reasons to avoid
-Could lose shape over time

Designed with surfers and extreme water-based lunatics in mind, this suit puts particular emphasis on stretch in the areas that require it most. That means there's plenty of give under the arms to allow for easier paddling motions, while panels in the legs make it simple to pop up on a surfboard or dig deep on a SUP. The E5 version of Flashlining is lighter than ever and features multiple layers that funnel water out of the suit quicker to keep the warmth locked in side, where it's needed most. Better still, the fuzzy warm stuff features throughout the Flashbomb, not just the vital chest and abdomen area, so you stay ridiculously warm in the water.

We found the suit incredibly easy to get in and out of, but even a hardy front zip closure system didn't completely negate the 'flushing' sensation occurs when cold water enters the back of suit. However, it's a super suit and the latest E4 neoprene is brilliantly stretchy and so easy to don, while the furry lining was arguably too hot for some of the sunnier days on the water in the UK, but we're not complaining...

Quiksilver Highline Pro 1MM wetsuit

3. Quiksilver Highline Pro 1MM

Best premium wetsuit

Material: neoprene
Seams: glued
Thickness: 1mm
Entry: zipperless shoulder
Main use: surfing
Reasons to buy
+Lightweight yet warm+Cutting-edge design +Super stretchy
Reasons to avoid
-Expensive-Non-traditional design

Our pick for the best premium wetsuit is the Quiksilver Highline Pro 1MM. This wettie is a bit of a badass, designed with the surfing pro in mind rather than the casual beginner. There's a lot of innovation here, an attempt to pack the warmth of a 3mm into a 1mm, which in theory gives warmth with unparalleled comfort and freedom of movement – a 1mm suit feels like wearing Speedos in comparison to a 3 or 4mm. Hand-sculpted in Japan from only nine panels of Japanese Limestone neoprene, the Highline Pro has no stitched seams and no zipper, saving weight and removing chafing points. 

What Quicksilver has done is create two entry systems to suit regular and goofy foot surfers, the idea being to reduce water flush during wipeouts by placing the entry on the non-lead side. The result is a sub-kilo weight, 1mm suit still rated for 13-18 degree waters – although there's an emphasis on high intensity, short sessions to stay warm. That said, if you want the ultimate surfer's suit just like the pros, then this is definitely the one for you, surfing the bleeding edge of technology – there's literally nothing else out there like it. 

SRFACE Heat wetsuit

Best mid-priced wetsuit

Material: limestone neoprene
Seams: liquid sealed and neoprene taped
Thickness: 3/2, 4/3, 5/4
Entry: chest zip
Main use: surfing
Reasons to buy
+Flexible and warm+Excellent value+One-year guarantee
Reasons to avoid
-Unable to try before you buy

With ‘try before you buy' being a common mantra when shopping for a new wetsuit, this must have presented online only, direct sales wetsuit manufacturer SRFACE with a fairly big headache when putting together its business proposal together. Fortunately for them, and us, they were obviously aware of the issue before launch, because they came up with a bullet-proof returns strategy allowing surfers to return incorrectly fitting wetsuits, even after use, providing it was within 30 days of purchase.

As well as having a no quibble guarantee, SRFACE's Heat range of wetsuits are excellent value for money and can compete with much higher priced wetsuits on performance. While they're not quite as stretchy as O'Neill's Hyperfreak range, there's still a lot of give in SRFACE's Japanese limestone derived neoprene and at no point were paddling or other body movements felt impeded by the 4/3 wetsuit tested. Unsurprisingly, give its name, the Heat wetsuit did a great job of maintaining warmth – aided by hollow fibre insulated panels to the chest and back, with neck, arm and ankle seals to help keep flushes of cold water at bay.

5. Olaian men's surfing 4/3mm neoprene wetsuit 100

Best budget wetsuit

Material: neoprene
Seams: glued & blind stitched
Thickness: 4mm chest/3mm arms and legs
Entry: rear zip
Main use: surfing
Reasons to buy
+Wallet friendly+Super-warm+Old-school rear zip
Reasons to avoid
-Get what you pay for

The Olaian 4/3mm wetsuit is a fantastic choice for the occasional surfer, or keen beginner looking for a warm suit. This really delivers on that promise, rated for an hour in ‘cold' water, which Decathlon defines as 12 to 17 degrees – you'll certainly be glad of a wetsuit at the lower end of this range. The 4/3mm neoprene may not have the environmental credentials of some of its peers, but it'll certainly do the job at hand. Glued and blind stitched seams, armoured knees and seamless inserts at crotch and underarms mean that comfort levels should be decent even on longer sessions too, which at this price point is more than enough. 

Finisterre Nieuwland 3E wetsuit

6. Finisterre Nieuwland 3E

The best wetsuit for women

Material: Yulex natural rubber
Seams: blind stitched and taped
Thickness: 3.5mm chest/2.5mm arms and legs
Entry: front chest zip
Main use: surfing
Reasons to buy
+Strong eco game+Warm+Super stretchy
Reasons to avoid
-Tight wrist seals don't suit all-Can size up small to start with

The Nieuwland 3E has received plenty of acclaim from around the industry, but the original version had one serious shortcoming – it was in men-only fit. This unfortunate oversight has now been rectified in full, with the 2020 launch of women's sizes. Made from eco-friendly Yulex natural rubber, the Nieuwland 3E is designed for UK waters by the St Agnes-based Finisterre, keeping you toasty in 14 – 18°C water with 3.5mm chest/2.5mm arms and legs – a good balance for maneuverability and heat retention. Warmth is boosted via a series of technical tricks, such as beefy wrist bands to improve the seal, a custom neck pattern to reduce flushing, and higher internal pile on chest and back, all intended to lock heat into the suit.

The eco-credentials don't stop with the Yulex either, with recycled polyester outer face and lining reducing the burden on the planet too. Overall, it's a great performer in colder waters, especially if the sizing is perfect for you (it'll stretch a little after the first 10 or so wears), and is jolly comfortable to boot.

Picture Organic Equation 3/2 FZ wetsuit

(Image credit: Picture Organic)

The most flexible eco-friendly wetsuit

Material: solvent-free EicoPrene
Seams: glued, blindstitched and taped
Thickness: 4/3, 3/2
Entry: chest zip
Main use: surfing
Reasons to buy
+Green credentials+Light and flexible+Quick drying
Reasons to avoid
-Not the most robust material

If you're looking for a new summer wetsuit, the Picture Organic Equation 3/2 FZ utilises flexible materials that feel good and won't hamper your surfing with production methods that are far less damaging than the ones used on most rival wetsuits out there. The Equation is constructed using neoprene made from 30 per cent recycled tyres and 70 per cent limestone (extracted using sustainable energy sources) and a lining that contains recycled fishing nets which is bonded in place using solvent-free glues.

Lighter and stretchier than other wetsuits with eco-credentials from the likes of Patagonia and Finisterre, the Equation's branded neoprene (EicoPrene) feels very similar to O'Neill's Technobutter. Like the O'Neill neoprene, EicoPrene is superbly flexible too and allows for a totally unrestricted feel. A lightly fleeced, quick drying lining covers the inside of the wetsuit to provide extra comfort and warmth. The only downside is that Equation is not as hardwearing as the other eco-friendly wetsuits and given how much flex there is in the neoprene, it's worth trying a smaller size than your usual wetsuit. Find out more in our Picture Organic Equation 3/2 FZ review.

Patagonia R3 Yulex FZ Full wetsuit

8. Patagonia R3 Yulex FZ Full Suit

Best wetsuit with impeccable green credentials

Material: Yulex & synthetic rubber
Seams: triple glued & taped
Thickness: 4.5mm chest/3mm arms and legs
Entry: front zip
Main use : surfing
Reasons to buy
+Stupidly warm+Environmentally friendly+Solid construction
Reasons to avoid
-High price-Tricky to get on and off

Next up in our best wetsuits guide is an eco-friendly option from Patagonia. This brand prides itself on its green credentials and its yulex line of wetsuits ditch the toxic neoprene of yesteryear and instead use a plant-based derivative for most elements. The suit itself is very well constructed and with 4.5mm of neoprene around your chest and back to keep you warm, this suit is ideal for use in the autumn and spring, and will do the job over winter if you avoid seriously cold days – check out the R4 for use on them.

This is the second iteration of Yulex neoprene which Patagonia claim is 20 per cent more flexible than the original. While the R3 is definitely stretchy enough to allow you to move relatively unhindered, it’s not quite as flexible as some on the market. However, unlike their more elastic rivals, Patagonia’s greener ethos means their wetsuits are designed to last as long as possible so the R3 will still be going strong when others have overstretched and started to leak.

The front entry zip is very robust and protects the wearer from any horrible 'flushing' moments, while all the seams are triple glued and then taped inside, as well as sealed on the outside for unrivalled water tightness. The hardwearing Supratex kneepads and ankle cuffs guard against damage from your board and anything else you might come across on land or water.

The R3 is definitely not cheap, but you’ll undoubtedly get more years out of it than most comparative wetsuits on the market. Patagonia’s wetties also come with an impressive lifetime warranty which also helps makes the price easier to swallow.

The best wetsuit: buying advice

A wetsuit comes in all shapes and sizes... quite literally. But by far the most important factor is the thickness of the rubber it uses, as this determines the warmth but also affects flexibility. You might also hear varying terminology when it comes to suit types but the ones we've focused on here are 'steamers' - those that trap a small amount of water between the body and rubber, then use your body heat to warm up the liquid layer and act as a thermal jacket.

Surfing right through a typical British winter used to be the pursuit of serious diehards only. Dedicated souls for whom early stage hypothermia was a price worth paying in pursuit of snagging a few uncrowded waves. Fortunately, improved wetsuit technologies now make the possibility of you losing the odd frostbitten extremity from a winter surf session unlikely outside of the Arctic Circle. 

A 5/4mm wetsuit will be thick enough to keep the cold away during the worst of the winter. However, if you feel the cold more than most, there are several surf brands offering 6/4mm suits these days. A wetsuit with an integrated hood is a good idea for deepest winter, but it makes the suit less suitable for cold autumn or spring sessions, when you’ll likely be surfing with the hood down, making the wettie more prone to flushing. As well an integrated or separate hood, wetsuit boots and gloves are both essential winter equipment too.

For British summer water temperatures, a 3/2mm makes the best choice, or perhaps a 4/3mm if you feel the cold or want a wetsuit that will also do the job in spring or autumn. Alas, it's important to remember that a wetsuit allows a small amount of water to enter the garment (unlike a dry suit, which locks all water out), so there will typically be a few moments when the sharp bite of the sea is tangible. But a good suit will stop 'flushing', or the scenario when new (and bloody cold) water enters the suit on a regular basis, which is the thing you really want to avoid. So, although appealing for their increased cosiness, once the thin layer of water has warmed via body heat, thicker suits will be cumbersome to wear and can drastically restrict movements when surfing, swimming and partaking in other cardio-intensive activities.

Size and fit is also extremely important, which is why most manufacturers will offer variations on the standard sizes. Long and short alternatives help cater for a variety of body shapes but every manufacturer is different. The best way to get a snug fit (that allows for plenty of movement) is to physically try on a range of suits, so we recommend going in-store or at least ordering a few and sending a bunch back.

Finally, suits are designed specially for numerous disciplines, meaning the latest surfing offering from O'Neill probably isn't suitable for a triathlon, which is why we've ranked a load based on their intended use and pointed out any additional features that we think are worthy of your attention.
