## Overview

The Arena Womens Open-Back Powerskin Carbon Air2 Kneeskin Racing Suit is a FINA-approved, ultra-lightweight, one-piece technical swimsuit designed for competitive female swimmers. Featuring seamless fabric construction, integrated Carbon Band technology for muscle support, and an open-back design for enhanced upper body mobility, it delivers a second-skin feel that reduces pressure and maximizes hydrodynamic efficiency.

## Description

The most lightweight of the Carbon series, arena's Powerskin Carbon Air2 provides hydrodynamic support to female competitive swimmers. The technical profile of the suit is comprised of one single piece of fabric, which works to reduce pressure on the hip area while providing a second-skin feeling of comfort. The absence of multiple seams means that the suit is easier to put on and take off pre-and-post race compared to other technical suits. The durable, lightweight Carbon Band technology provides a mild compression that helps to stabilize and activate key muscles, without sacrificing comfort and flexibility. The internal lining reduces pressure in the chest area to allow for a wider range of motion, and an open-back design further increases this efficient mobility. World Aquatics (FINA)-approved.

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.
