ORCA Men's S6 Full Sleeve Wetsuit FLEXIBILITY - 2mm 39cell SCS coated Yamamoto underarm, shoulder and arm panels combined with a flexible Powerstretch lining provide a superb range of motion and improve flexibility. BUOYANCY - SCS coated Yamamoto front panel and a 4.5mm lower back panel provides maximum buoyancy and freedom of movement in the water. COMFORT - With less panels on the legs and arms, both functionality and comfort of the suit has been increased from its S5 predecessor. 39CELL - Yamamoto 39cell is an extremely flexible neoprene which supports an uninhibited natural swimming motion. 39cell extends to a 513% elongation rate, meaning this material is sure to move with you. Added benefits of zero water absorption and zero weight variation can mean only one thing: more speed. A fine balance between buoyancy and flexibility, 39cell is a durable material which will stand the test of time and distance, representing the best neoprene available in its class. SCS - Acting as a coating over closed-cell neoprene, Super Composite Skin (SCS) has become the benchmark for coating the smoothskin neoprene used in triathlon wetsuits, to reduce friction and increase speed through the water. The micro-cell structure of the SCS coating repels water when in contact with air and reduces surface resistance when in contact with water.
