The knee-length Speedsuit from ZAOSU An unrivalled swimming sensation in mild water temperatures! With the Speedsuit (with knee-length leg cuffs), ZAOSU presents an innovative suit for open water competitions and training in mild water temperatures. The ZAOSU Speedsuit is made of high-quality Hydro-Tech material, which prevents the body from cooling down (especially in the torso area) and also provides light buoyancy. Combined with a special surface coating, the water resistance is reduced and the gliding properties improved. High-quality compression fibres, which extend the performance of the muscles, enable a more energy-saving and faster swim in the long term. The off-the-shoulder X-design at the back maximises freedom of movement. Flat seams and a low-cut neck offer optimum comfort. A low-resistance zip with protective insert and fabric cord on the back make it easy and comfortable to put on and take off. The ZAOSU Speedsuit - your choice for speed and flexibility in the water! This suit must not be worn at events where neoprene is prohibited!
