Steamer in 6mm thickness with SilverSeal. All water entry points (neck, wrists, ankles) are designed to minimize water exchange between the inside and outside of the suit. Ankles and wrists feature GlideSkin seals plus a zipper on the outer neoprene layer. When used in combination with the 2ndSkin shorty Wetsuits you have a real barrier to water protecting you. A real second skin! Supratex knee pads and Spine Pad complete an already rich suit. The She Dives version is custom- designed and pre-shaped for a superior fit to the female anatomy. The inside of elbows and knees is pre-shaped as well so as to better accommodate arms and legs.
