Premium Japanese Yamamoto 39 Cell neoprene is buoyant but still flexible and varies in thickness throughout the body of the wetsuit, moving your centre of buoyancy lower, preventing sinky legs and putting you in perfect horizontal swimming position. Super Composite Skin (SCS) hydrodynamic coating reduces surface drag for more speed. Embossed concave water entrapment zone on arm sleeve, enhances power and feel of water whlist the floating zip panel increases movement for improved distance per stroke. Rollbar technology ensures less buoyancy on perimeter of wetsuit, allowing snappier side-to-side rotation and eliminating dead spots in your freestyle. Our neck panel eliminates seams to improve comfort and reduce chafing whilst the often-overlooked internal liner is engineered for 520% stretch to ensure comfort and low absorption.
