Lots of compression!
We got the Arena Carbon Air tech suit for my daughter this season, and honestly it lived up to the hype. Right off the blocks you can feel how light it is — it really feels like a second skin in the water instead of something heavy or restrictive. The fabric and integrated carbon bands give just enough compression where it counts without making her feel locked in, so she could move freely through every stroke.  What we noticed most on race day was that it glided so much smoother through the water — less drag, more confidence, and way more speed off turns. The one-piece design and great range of motion means she could breathe and rotate without feeling stiff.  And the best part? She hit a state-level time wearing it — that’s the real proof right there. 🥇 Perfect for meets if you want comfort + legit performance.

See through
Loved the color but beware, it was a bit too see-through for a 17 year old. After it’s wet, her chest was exposed. Not cool.

Augmente les performances !
Comme ce maillot contient 1% de carbone, il est très difficile à enfiler la première fois (il faut bien suivre la méthode), il est très confortable, la compression se fait aux bons endroits. J'ai pris une taille de + qu'un maillot compressif de compétition sans carbone de la même marque. Mon temps au 100 m 4 nages a été inférieur de 4 secondes !!
