It is certainly not for nothing that most triathletes prefer to swim in a triathlon wetsuit, even if it means losing a few seconds while undressing.

There are combinations specially designed for triathlon.

In order to choose your triathlon wetsuit, there are several criteria to take into account. First of all, before thinking about choosing your swimming suit, it is important to determine a budget!

Our recommendations when trying on the garment

Here is a non-exhaustive list of tips for enjoying an adapted swimming suit:

Water entry and circulation should be kept to a minimum. For this, the triathlon suit must be adjusted as well as possible without causing compression points on the neck, arms, armpits, and knees. Thus, the suit should stick to the skin all over your body.

When trying on, prefer a neoprene swimming suit without air pockets, because these will soak up water and therefore cancel the thermal protection effect.

The cutouts at the armpits and crotch, as well as the back closure, facilitate ease on a triathlon wetsuit. Do not hesitate when trying on to do crawl or breaststroke movements to see the elasticity of the triathlon suit.

If you want to have a little more lift thanks to the buoyancy of the triathlon wetsuit, and you dread the cold, we advise you to opt for a full triathlon wetsuit that is thicker in sensitive areas and more pleasant in areas of shoulder friction. , knees…)

In addition, also remember to protect yourself from the cold in the head. For this, neoprene swimming hoods are particularly suitable.
