For swimming, cycling and running in the same suit, the trisuit is a staple. Its benefits: dries quickly after swimming and is comfortable for cycling thanks to a pad that does not hamper your run. Triathlon suits are worn like cycling shorts: with no underwear.

None! It's the same type of triathlon outfit, a 3 in 1 suit: pick the term you prefer.

Yes… and no. 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 24°C and makes it compulsory when the temperature goes under 16°C. Between 16 and 24°C, it's up to you.

The woman model follows the female body shape, with good breast support and a slim fit at the waist. The rest of the fabric is looser for extra comfort. At the shoulders, sleeveless women suits are less cut out than men versions to provide more coverage (so that the sports bra is not visible).

A practical difference, not a technical one: with a top and bottom, pee breaks will be faster than with a suit. You can also change the combinations, for example use a cycling jersey, a running t-shirt, etc. In terms of comfort however, there's no difference between a top and bottom and a suit: the material provides more comfort for the cycling section.
