This wetsuit has a base of 2 mm nylon covered neoprene that provides great mobility and ensures free movement of the hip area when running. Nylon covered neoprene inside and outside makes the suit durable and 3 mm panels on the chest and upper thighs increase buoyancy and improve swim position. The wetsuit includes a front and back zip for ease and 2 inner pockets. Neon coloured arms and back make for good visibility in the water. It also comes with a small, effective whistle for security.
