A good wetsuit makes you faster in the water: it floats you, keeps you flat and protects you from the cold. A bad one chafes, tires your shoulders and lets water in. We compared eight models, from an €85 sleeveless suit to a €689 flagship, and explain water temperature rules, how to get the size right and how to make it last. Prices from Spanish/European stores on October 5, 2026.
How we compared
- Use: triathlon (short cuffs and quick exit) or open water swimming.
- Thickness: up to 5 mm in the legs and hips for lift; 2 mm or less in the arms for movement.
- The water temperature range it's built for.
- Fit: snug like a second skin, with no air pockets or chest pressure.
- Buyer ratings and real price.

Rules: when you can wear a wetsuit
Water temperature decides. Under World Triathlon rules for age-groupers at standard distance, a wetsuit is mandatory below 16°C (60.8°F) and banned from 24.6°C (76.3°F). In between, it's optional.
Most organizations cap thickness at 5 mm. Ironman and some long-course races have their own thresholds, so always read your race's athlete guide.
That's why triathlon wetsuits are built for 16 to 24°C water, as the Van Rysel suits state.
Triathlon vs. open water
A triathlon wetsuit is built for speed: thicker legs for lift, thin arms, shorter sleeves and legs, and a zipper designed to come off fast in transition.
An open water suit, like the Nabaiji models, puts comfort and price first. Thickness is more even, it floats less and it isn't optimized for a running exit. You can race in it, but you'll lose some time.
Sleeveless and LongJohn models leave your shoulders free. They're good in mild water and for swimmers whose arms tire in sleeves, at the cost of less warmth and lift.
How to choose your size
Check the brand's chart using your height and chest size; weight matters less. If you're between sizes, generally go with the one that fits your chest best.
Dry, it should feel very tight. There should be no air pockets in the back or armpits, but you must be able to raise your arms and breathe deeply without pressure.
Put it on slowly, with gloves, working the neoprene up from your ankles. Most tears come from fingernails while putting it on.
Care and lifespan
Rinse your wetsuit in fresh water after every use, especially after the sea. Dry it in the shade, inside out, on a wide hanger.
Never tumble-dry or iron it, and don't leave it in the sun or folded for long. Decathlon recommends hand washing at 40°C max.
With this care, a wetsuit lasts several seasons. High-end suits with thinner shoulder neoprene are more delicate and tear sooner if mistreated.

Verdict
For your first triathlon, the €140 Van Rysel 3/2 (men's or women's) is the smartest buy: it floats, it's built for transition and it has good reviews. If you only swim in the sea, a Nabaiji is enough. If your legs sink and you want more quality, get the Orca Athlex Float. And if you race seriously, the Van Rysel x Deboer offers high-end performance for much less than the Zone3 Aspire.
Frequently asked questions
What water temperature requires a wetsuit in triathlon?
For age-groupers at standard distance, World Triathlon makes it mandatory below 16°C (60.8°F) and bans it from 24.6°C (76.3°F). Check your race guide: each organizer may differ.
What size triathlon wetsuit should I get?
Use your height and chest size on the brand's chart. It should be very snug when dry, with no air in the back, but it shouldn't squeeze your chest when you breathe.
How long does a triathlon wetsuit last?
Several seasons if you rinse it in fresh water, dry it in the shade and put it on carefully. Fingernail cuts while putting it on are the most common cause of tears.
Can I use a surf wetsuit for triathlon?
It's not a good idea. It's usually stiffer in the shoulders and isn't designed for freestyle swimming. It may also exceed the 5 mm limit.
