🏊‍♀️ 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

1️⃣ Was it hard to put on? That’s usually a good sign!

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:

Better hydrodynamics
Less muscle fatigue
Optimized blood circulation

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

2️⃣ No visible air pockets

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

3️⃣ You can lift your arms without forcing

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:

Faster fatigue
Irritation and muscle pain

4️⃣ No irritation, even after 200 m

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:

Reduced performance
Risk of injury
Bad race experience

5️⃣ In the water, you almost forget it’s there

The right size is the one you barely feel: not too rigid, not too stretchy.
It follows your movements naturally, without discomfort.
Impact:

Better glide and speed sensation
Less technical fatigue
Optimized result

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