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 gilet 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: 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.
