🏊‍♀️ How to know if your wetsuit is the right size?

Before your next competition, take 3 minutes to check that your racing swimsuit fits properly.

The right size gives you comfort, performance, and freedom of movement.

👇 Here are 5 simple signs to check

A racing swimsuit should feel very tight.

👉 If it slips on easily like a regular swimsuit, it’s too big.

Technical fabrics are designed to sit close to the skin and slightly compress the muscles.

Impact:

⚠️ Difficult ≠ painful: if it hurts, it’s too small.

If the suit is too big, it creates folds in certain areas: back, hips, thighs…

These folds become air pockets that let water in: guaranteed parachute effect!

Impact:

Water gets in

Less compression = less performance

Unpleasant floating feeling

A good racing swimsuit should not restrict movement around the shoulders and neck.

If the size is too small, it pulls on the traps and shoulder blades.

Impact:

Flat seams and technical fabrics are designed to reduce friction.

If you come out of the water with redness under your arms or around your neck, the size — or cut — is not right.

Impact:

The right size is the one you barely feel: not too rigid, not too stretchy.

It follows your movements naturally, without discomfort.

Impact:

💡 If you swim “free” and fast: your racing swimsuit is perfect!
