Arena engineered Carbon Air to have all the benefits of compression swimwear with the added advantage of ultra comfort. Horizontal bands of their trademark carbon technology intelligently compress when and where you need it with zero restrictions. Combined with Arena's lightest performance fabric yet, Carbon Air is super easy to get on and comfortable for long periods of time. The smart stretch shoulder straps reduce unwanted pressure, and the open back gives you extra freedom of motion across different strokes. With the water repellency and durability you would expect of a medal-winning suit.
