Good quality tri suit

Tried it on a 60km bike ride and on a few running laps around the track. Felt light and comfortable.

icon-circle-checkmark verified purchase
Almost perfect, my first tri-suit.

Awesome parts: - can feel the difference on my swim, feels like am easily going thru water. - sizing is great, love the design Improvements: - the end stitch near the knees pokes with the inner thigh skin and that is painful at start and gets annoying thru the run. - the material between thighs brushes thru the bike saddle and makes noise! Friction is number one that us athletes are eliminating from our gear. In the long run will make my bike saddle scratched and old faster, not to mention the suite itself will get damage soon with it brushing thru the saddle. Annoying! - the stitching are not so good, had to bring it back as some of the stitch near the crotch came of after 1 use. I dont know about you but we dont wear underwear with tri-suitr and we dont want our privates popping out during training because of a bad stitching. - again the stitching part, this time it’s on the padding. If that comes loose, which it did in my case, then the padding wont be secured and that means movement of the padding and that can lead to chaffing. - more color option, make us look bad a$$ out there!

Super combinaison trifonction mais…

Super combinaison trifonction mais un bémol pour le bas des jambes qui est pas top (ça baille un peu)

Excellent produit

Combinaison achetée principalement pour rouler par temps chaud, super confortable de ne pas avoir de bretelles du cuissard et surtout un séchage rapide. Taille identique à celle de l'année dernière dans le côté "panneau publicitaire". Seconde peau, pas de pli gênant. Taille un peu plus grand que ce qui est donnée par l'outil de choix, je suis entré 2 tailles (L et XL) j'ai finalement pris la L. Reste les élastiques au niveau des bras et de cuisses qui sont un peu plus serrés, mais dans la XL pas assez de maintient a la taille. Tout le bas du dos et le haut des fesses est doublé, par de transparence "gênante", La peau de chamois, même si faite pour le triathlon, passe très bien pour des sorties de 70km sans problème, a voir pour plus... Très content de mon achat

impeccable bravo D4!

Muito bom

Um fato muito confortável e fresco, em relação aos antigos que embora sejam igualmente muito bons e fiáveis mas é notável a qualidade e evolução em torno da prática desportiva com novas custuras menos saliente e a densidade do tecido menos abrasivo. A relação preço qualidade é excelente... Recomendo

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. - For cycling, its fine, soft skin adapts to your body shape and improves sitting comfort. The trisuit acts like cycling shorts, to be worn without underwear. - For running, its fine gel skin is almost unnoticeable: you can run lightly. All you have to focus on is crossing the finish line!

Stay permanently dry!

The lightweight component of this trisuit 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! This trisuit also has mesh areas which wick away perspiration where sweating is most profuse on your body: under your arms and along your spine.

The small details that change everything!

- This trisuit has thermoformed elastic at the arms and thighs, so doesn't move during use or when putting on a neoprene suit for the swimming leg. - The full-length zipper opens like a vest and allows you to ventilation during the race. It also makes toilet stops a lot easier! - The top of the trisuit is made of very lightweight material for more comfort and quick drying. The “shorts” part offers very good support.

A product designed to carry nutrition

To get to the finish line of a short-distance triathlon (3 to 6 hours of exertion), you need to eat! This trisuit has 2 thermoformed pockets on the thighs: you won't feel them as they are seamless and zipper-free, plus the products they hold are under tension and don't move. There are also 2 net pockets at your lower back. In total with these 4 pockets, you can carry 10 bars and/or gels for refueling!

Trisuit, triathlon suit, triathlon trisuit ... are there differences?

None! It's the same type of triathlon outfit, a 3-in-1 suit: you pick you preferred term. 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: For swim distances up to 1500 meters British Triathlon rules forbid the wearing of a wetsuit when the temperature is above 72°F and make it mandatory when the temperature goes below 57°F. Between 57°F and 72°F, it’s up to you.

This trisuit was tested by a dozen triathletes, throughout its development, for training and competitions. Fitting, use, seam tests, no effort was spared by our internal ambassadors and external users!
