For wind sports, this is the warmest neoprene drysuit we know of. Constructed in a combination of 5mm thickness in the torso, and 3mm thickness in the arms and back knees and having a watertight self-sealing across the shoulder zipper, this drysuit is perfect for people whose best sailing comes in the coldest months of year.
All seams are sealed with glue and tape. Heavy duty dry zipper is the best we have found. Nylon II (waterproof) panels in the saddle, knees, and shoulder yoke provides durability.
Updated with ADV WindSkin material in the chest, back, thighs, and arms. Smoothskin seals on wrists and ankles. Flexible kneepads will not grate on your knees. "Super-flex" collar for easy entry and exits.
