Men's sleeveless wetsuit for open water swimming and other water sports. The suit is made of DSSS treated neoprene (without GLIDESKIN coating) in different thicknesses - on the belly, chest and back the neoprene is 3 mm, which provides additional buoyancy. In other areas of the wetsuit it is 2 mm thick, giving you greater freedom of movement and flexibility. DSSS neoprene combines lightness, flexibility and durability to provide good buoyancy and good thermoregulation while swimming. When correctly fitted, the suit sits perfectly and does not chafe or limit movement. The flat seams do not chafe even during long swims. The YKK ZIPPER (Japan) is on the back and gives you comfortable one-hand access, allowing you to quickly put on or take off the wetsuit. The zipper has an external flap to prevent it from opening accidentally and is fastened with Velcro. The cropped cut with exposed arms and legs makes it ideal for triathlon and warm-weather freediving.
