Great value for money I used for a triathlon

Material feels great I used for a short triathlon. I'd buy the same brand again

Great item for its price

Just completed a Sprint Triathlon in this suit and I've had a few training sessions in it. Padding is great for the bike but not invasive on the run, dries really fast. For the price I 100% recommend it.

Needs 1 thing

The zip head has now left a rub spot on 2 separate occasions, there needs to be a bigger neoprene tab on the inside for it to sit on, and there for not rubbing on the skin.

good budget suit for a beginner

The 4 stars are based on the value for money rather than quality. This was my first trisuit so I saw this as decent value for money, however, given I know I'm going to be doing more I do wish I had invested a bit more. I performed perfectly well in the Sprint tri, but anything longer would need a better suit. Fit: the torso is too long - bunching Comfort: maybe my muscles are too big(!) but found the elastics too tight. Suit certainly stayed in place round the legs, but my higher-end cycling bib shorts are likley similar to high end trisuit ie. elasticated less concentrated. Pouch: should not be called a 'pocket' in product description. This swung my choice to buy this suit, but it is so tiny it's pointless. I put a gel in there and it fell out. realistically all it can hold is a few sweets but nobody would use it for that. Overall: it's fine for beginners. If you're stingy like I was in this instance, think carefully about how much value you'll get with another.

I stumbled upon this product while looking for a cycling bib. Bought it because the design visual looked aesthetically pleasing and don't regret one bit. It fits my body like a glove and I use it for cycling at the moment. Great stitches & good textile; the ones that feel well on the skin. Just had to leave a quick note of appreciation.

The product was to small for me, but perfect for a friend

Swimming training sessions

I use it for swimming sessions because it holds on body the HR chest strap, otherwise it just rolling down the body especially during a drill on max. I use it for cycling barely, but I have to say that it is definitely compress trisuit, which is rather positive thing. This is my second one.

Triatlon kombinéza

Perfektní výrobek. Dobře se v ní plave, jede na kole i běhá.O dvě minuty kratší čas na stejné trati, díky úspoře času s převlékáním v depu... 😅

Pánská triatlonová kombinéza

Kvalita odpovídá ceně, rychle schne, mám obavu o trvanlivost zipu.

icon-circle-checkmark verified purchase

Za tu cenu asi nic moc cekat nelze. Ale cyklovlozka je opravdu mizerna i po kratkem triatlonu sem z ni odrenej.

The trisuit = a 3-in-1 product!

The trisuit is an iconic accessory for triathletes and a staple for triathlons: - For swimming, its fabric is similar to that of a swimsuit, and its inner foam chamois is perforated therefore doesn't get waterlogged. - For cycling, the foam chamois improves sitting comfort. The trisuit acts like cycling shorts, to be worn without underwear. - For running, its fine chamois provides comfort and low weight. All you have to focus on is crossing the finish line.

Dry quickly!

The fabric that this trisuit is made from allows super fast drying during your swimming/cycling transitions so that you don't stay wet while you cycle. And yes, you can swim with your trisuit on under your neoprene suit to save time during this transition! We also used a large mesh band to wick away perspiration where sweating is profuse: at the spine.

The small details that change everything!

- This trisuit has a silicone strip at the thighs, so that the bottom doesn't move during use or when putting on a neoprene suit for the swimming leg. - A front zipper going down to the navel allows you to ventilate during the race, and ensures quick dressing! Plus, this zipper has an internal protection strip to avoid friction. - Finally, the armpits do not come into contact with the fabric so do not chafe.

A trisuit adapted to your body shape!

This trisuit was designed to mold to men's body features. Overall, the fabric used for this trisuit is more lightweight on the top and has slightly more support on the bottom. It provides all the support and comfort you need for natural movement, without compressing. The internal foam perfectly molds to your male body shape.

A product designed to carry nutrition.

To get to the finish line of a short-distance triathlon (1 to 3 hours of exertion), you need to eat! This trisuit has an easily accessible pocket on the right thigh: no need to fumble in your pockets blindly to reach for fuel — you can see everything! This pocket can hold up to 2 bar and/or gel products and is thermoformed: you won't feel it as it is seamless and zipper-free, plus the products it holds are under tension and don't move.

Trisuit, triathlon suit, triathlon trisuit... what's the difference?

None! It's the same type of triathlon outfit, a 3-in-1 suit: it's up to you to use the term you prefer. Not to be confused with a neoprene wetsuit which provides buoyancy and insulation for the swim.

Should i put on an additional suit to swim?

It depends on the water temperature! The neoprene suit provides buoyancy, an asset for the swim leg. Good to know: The French Triathlon Federation forbids isothermal swimsuits when the water temperature is above 75°F and makes them compulsory when the temperature goes below 61°F. Between 61 and 75°F, it's up to you.

With or without underwear?

We recommend you wear a sports bra for good chest support, however we encourage you not to wear briefs or boxer shorts to avoid any unnecessary chafing.
