A pro level racing wetsuit, ideal for triathlons and open water swim competitions, the Aqua Sphere Racer promotes easy flexibility in the water with optimal buoyancy. Bio-stretch 2mm panelling under the arms and across the lower back enhance freedom of movement for a full range of motion and better swimming performance. A 5mm Aqua Drive core body panel, and a 4mm lower back panel provide the added buoyancy, helping position the body better in the water to be more streamlined and reduce drag. Thermo-Guard technology on the chest, shoulders and legs lock in body heat, and an Aqua-Flex collar seal keeps out water and reduces chafing. Quick release ankle panels and an easy-pull deep back zipper aid a faster transition between triathlon stages.. Material: 100% Neoprene
