Wetsuit finder
No quiz, just the three things our shop team asks everyone who walks in.
Winter needs a hooded 5/4, spring and autumn a 4/3, summer a 3/2.
Chest zips keep more water out; back zips are easier to get into.
Measure chest, waist and height, then check the size chart. Snug is right.
Keep warm
Boots, gloves, a hood and a robe: the difference between a short session and a long one.
Warm in, warm out
Waterproof shell, a fleece-like recycled lining that dries fast, a hood big enough for wet hair and pockets big enough for a flask. Change in the car park without an audience.

How we make it
Wetsuits are hard on the planet. Here is what we do about it, and what we have not solved yet.
Our suits use limestone-based neoprene and linings spun from recycled bottles. It is better, not perfect: we are still testing plant-based rubber.
Send any Swell wetsuit back for a seam or zip repair. Most cost £15 to £30, and it keeps a suit in the water for years.
Post us a worn-out Swell wetsuit and we pass it to a UK recycler that turns neoprene into yoga mats and dog toys.
Reviews
“I emailed my height and chest and they told me exactly which suit to order. It fitted first time.”
“The changing robe has made winter sessions bearable. Warm before and after, and it dries fast.”
“They repaired a split seam on my old suit for £20 and posted it back in a fortnight. It is still going.”
