Product Customer Reviews

I'm at UK 12 and bought the medium. It's a little big but that just makes it easier to put on, plus you can wear a rashvest. The extra thickness of this suit means I can cold water swim for longer. Not being 100% glideskin means you are less likely to pierce the suit when putting it on. It is robust. I swim 3 to 4 times a week in an outdoor cold water lido. This suit has been going strong for over a year and doesn't look like it's going to need replacing anytime soon.
I'm a surfer who has been wearing wetsuits for over 30yrs. This suit fits well and buoyancy is perfect and surprisingly warm for such a wafer thin suit. I just cannot see how this will last beyond a month... I know how to put on/remove, rinse, dry but this looks beyond fragile! Will update if necessary! Hoping for a miracle!!
The size guide says L = UK 12-14 yet when the suit arrived it had L = UK 18 on it. Way too big. Its not hard to get the sizing right or consistent... Product look sgood and would be good if the sizing was right, its just so teadious having to send it back.
The fit is great, it is actually easy to get on and off, though fits perfectly. The legs left in the water, really buoyant, I’m not a confident swimmer and this wetsuit is great support in the water!
This came recommended by a friend and I bought it for outdoor swimming. I've not yet tried it in the water but it's a great fit. I'm 5ft 7 and a 12-14 and bought a large
This was a purchase for introduction to open water swimming in November in the midlands so intro temp at 9.5 degrees then getting colder. Gone to 6.4 degrees and been fine for 20 minutes so far.(with neo socks and gloves). Amazed at how warm it has kept me. Great fit (I’m a 10-12 and this was medium). Not too buoyant in the water and
I'm very new to open water swimming so didn't want to spend a fortune on a suit. I think this one is great for the price point, but sizing does run a little small. I usually wear an XS at Decathlon but had to size uk to S - for reference I wear a UK 6. Have now also worn it for a race and it performed great, very happy with purchase
Never bought one of those before. Fits as expected. Haven't used it yet.
The perfect fit for my wife
Good value. Keeps me warm in cold water. Zip design a bit counter intuitive and hard to fasten at top but once done works well.
I just did my first open water triathlon is this wetsuit. I have nothing to compare it to, but absolutely did the job for me. Yes, I needed a mate to zip me up, but the zip is designed that way for quick transition (and worked well). The slighter shorter ankles and arms made removal easy (with the exception of the timing chip leg, but that was never going to be easy!) I should say, I’m 162cm and they weren’t noticeably that short. I know people say the wetsuit’s fragile, but no problems as yet to report. For the price, for a novice open water swimmer like me, I absolutely recommend it. Thanks decathlon! You saved me lots of pennies :)

Neopren byl objednávaný pro dceru, velikost jsme zvolili po předchozím dotazu, požadovanou informaci jsme obdrželi velmi rychle a skutečně sedí jako ulitý. Dcera je spokojená, neopren nadnáší, tepelná izolace super (vyzkoušeno v rybníku za dubnových teplot, pobyt ve vodě vždy cca 1 hodina/4 km). Oblékání i svlékání je jednoduché, stačilo 2x vyzkoušet a pak už to šlo samo.
Passt auch für Männer

Why is the zipper on this trifunction suit inverted?
We chose an inverted zipper so it's easy get out of your trifunction suit for your 1st transition. Easy to take off with a natural upward movement. The inverted direction also prevents your zipper being "unintentionally" opened by other competitors during the swim phase.
Why wear a neoprene suit for a triathlon?
Depending on the water temperature, wearing a neoprene suit for a triathlon is: - Compulsory if the water temperature is below 61°F - Authorized if the water temperature is between 61 and 75°F - Banned if the water temperature is equal to or over 72°F
Is there any point in wearing my neoprene suit if it's not obligatory?
Yes, yes and yes! A neoprene suit provides more buoyancy and helps you glide, as well as keeping you warm. Depending on your swimming level, you can generally expect to reduce your time by between 1 min 30 and 3 minutes over a distance of 0.6 miles. So it will be a precious help even over short distances!
How to choose the right size of suit
It's just as important to choose the right size of neoprene suit as it is too choose the right model. The neoprene suit should be worn just like a second skin without feeling oppressive, and should provide you with freedom of movement. We designed this Aptonia SD suit with slightly shortened cuffs to make it easier to take off.
