The absence of side seams produces even stretch throughout the suit for a supremely comfortable fit that feels like a second skin, giving the swimmer the sensation of no constraints in the water. The suit's one-piece construction reduces overall water absorption, thus creating less drag and making the swimmer feel lighter in the water. The lack of side seams dramatically reduces stress on the suit. This sporty style utilizes arena's most advanced and longest-lasting 100% Polyester MaxLife fabric and is designed to deliver maximum comfort, range of motion, and chlorine resistance for the most demanding competitive swimmers, while maintaining superior softness, durability, and performance all season. The arena ONE training collection is smart, sporty and sophisticated, and targets two primary consumer categories. Competitive swimmers who seek out the latest in swimwear technology for training as well as racing, and will be drawn to the suit's better glide and second skin attributes inherited from Powerskin R-Evo One racing suit design. Fitness swimmers will love the ONE suits for their superior comfort, extreme durability and unique design, along with the feeling of being one with the water.
