The Athlex Flex wetsuit offers a combination of high elasticity and medium buoyancy, for swimmers who are able to maintain a good position in the water without added buoyancy. The thin materials in the upper body and those of medium thickness in the legs result in a wetsuit that provides maximum freedom of movement. 39+The increased flexibility of Yamamoto 39 neoprene, combined with the high elasticity of Inifinty Skin 2 lining, provides open water swimmers with maximum freedom of movement. Thanks to this combination, 35% less force is required in fast movements than in conventional neoprene. For slow movements and wider strokes, 45% less force is required than in conventional neoprene. SCS coating also helps reduce friction and water resistance, improving hydrodynamics and increasing speed. 39 FSElasticity, maximum flexibility and total freedom of movement are brought together thanks to the combination of Yamamoto 39 neoprene, Infinity Skin 2 lining and Smoothskin surface finish. With this combination, the open water swimmer will use 35% less force in fast movements and short strokes, while slower and wider movements will require 45% less force than any other conventional neoprene. 38+Yamamoto 38 provides more compression for a better fitting wetsuit, for greater comfort when swimming in open water. For greater hydrodynamics, SCS coating is used which reduces water resistance, increasing speed.
