Streamlined and ready to overtake the competition, the Zoot Wikiwiki Wetsuit has been designed to feel like a sleeveless wetsuit thanks to the 0.3mm Yamamoto Mark III super stretch neoprene utilised in the arm and shoulders. Giving excellent hydrodynamics and working to speed up stroke recovery times with a Waterwing catch panel that brings the forearm into a vertical position as quickly as possible. With a comfortable fit and excellent flexibility, you can perform at your best and never feel restricted in the open water, while quick release ankle panels allow for a speedy transition. Waterwing Catch Panel Increasing the surface area on your forearms, the Waterwing catch panels utilise the same principals from wind tunnel testing to create water turbulence at the stroke phase and reduce the vertex of water around the forearm to reduce drag and quickly bring the forearm back to a vertical position. Yamamoto Aerodrome Neoprene with SCS (Super Composite Skin) Coating Utilising the highest grade of rubber available, this wetsuit is crafted from the worlds best neoprene made at the Yamamoto Corporation in Japan. Delivering increased flexibility and durability while being better for the environment than traditional neoprene, the Yamamoto wetsuits absorb very little water and are naturally lighter and warmer. Yamamoto Aerodrome is designed with air bubbles between the fabric to make it lightweight and up to 30% more buoyant. Finished with a hydrodynamic SCS coating, you will be able to quickly glide through the water as drag is reduced, repelling water and protecting your wetsuit by reducing the possibility of rips and tears. GLIDEflex Technology & OKD (Optimal Kick Design) With maximum flexibility in the arms and shoulders, you can make the most of each stroke and travel further with less fatigue. GLIDEFLEX panels work to increase the stretch for maximum muscle and lung expansion while OKD, Zoot's propriety leg patterning increases kick velocity, frequency and efficiency so you can perform at your best. AQUAlift Buoyancy Profile Designed with 5mm neoprene at the mid/lower front side of the body, this highly buoyant wetsuit works to raise both the legs and torso our of the water so you are held in the ideal swimming position for maximum efficiency. DORSALflex Zipper Improving stretch and lung expansion, a 2mm neoprene panel around the back zipper eliminates the restrictive feeling when zipping up on traditional wetsuits and allows the suit to stretch with your body's natural movements.
