Zoot Z Force 3 Wetzoot Wetsuit Introducing the Z Force 3.0. For added comfort the Z Force 3.0 Wetsuit has Glideflex grooved panels to increase stretch for maximum lung expansion, shoulder rotation and shoulder extension. The Zero water comfort neck panel eliminated neck constriction to create an extremely low profile neck seal that limits water entry and stops chafing. OKD, Optimal Kick Design is Zoot’s proprietary kick design that helps your legs stay in the natural body position to kick. Designed with Yamamoto Cell 39, the Z Force 3.0 is an exceptionally comfortable high-performance wetsuit. Super Composite Skin (SCS) is a hydrodynamic coating that improves swimming speeds by reducing drag allowing the suit to glide through water more efficiently. Due to its ultra low surface friction, SCS coating improves neoprene’s surface abrasion resistance, durability, and strength. Aqualift in the rear of the suit provides maximum buoyancy raising your legs and torso in the water to get you in the correct position for increased power and speed. Yamamoto 39 Neoprene provides stretch and comfort from the extremely lightweight and low-density rubber, the lower the density the more buoyancy you get and the more buoyancy the higher speeds you can get up to. 2mm of neoprene around the zipper provides superior stretch for improved lung expansion. Dorsalflex zippers allow the zipper to stretch with the body instead of restricting like traditional wetsuit zippers do.
