Zoot Z Force 2.0 Sleeveless Wetzoot uses Yamamoto Cell 39 Neoprene which is extremely lightweight and low-density and provides plenty of stretch and comfort. The lower the density the maximum the buoyancy which equals more speed. The suit features grooved GLIDEflex panels that increase stretch for maximum lung expansion, shoulder rotation and extension as well as an Optimal Kick Design which is a leg patterning that makes the wetsuit work with your anatomy rather than fight it. The Optimal Kick Design increases kick velocity, frequency and efficiency.
