Orca have focused on many of their top-quality materials to help make the S6 one of the best choices for anyone trying to improve swimming form. To accomplish this, Orca turns to their Yamamoto 39cell material. Yamamoto provides some of the best high performance neoprene in the world. The 39cell acts as an extremely flexible neoprene that has a greater elongation rate than most neoprenes so that it will move with you. It has an SCS (Super Composite Skin) coating over the closed-cell neoprene, designed to absorb no water, gaining no extra weight along the way. A perfect balance between buoyancy and flexibility, the Yamamoto 39cell material is combined with a flexible Powerstretch lining to provide an excellent range of motion and improved flexibility. The front panel uses 5mm SCS coated Yamamoto neoprene to offer a maximum of buoyancy. The same material is used for the lower back panel to help you move naturally while giving you a little extra lift in the water. On the inside, Orca's unique high stretch nylon, InfinitySkin lining plays an essential role in the exceptional level of flexibility. InfinitySkin allows the wetsuit to move dynamically through your swim stroke. And the HydroLite panels are used to make the suit that much easier to remove in important transitions.
