The Akona Skin Suit provides maximum comfort for tropical environments. Made from 10 oz. (283.5 g) polypropylene, soft brushed lining and flat-lock stitched construction form a comfortable fit to use alone or as layering garment. Wearing a skin suit under your normal exposure suit can keep you much warmer than without. The Skin Suit retains the water that enters your wetsuit and keeps it from flushing out of the wetsuit thus helps retain your body heat. Other features include ankle & thumb stirrups which won't allow the suit to ride up when in the water or when worn under your exposure suit. Skin Suit has a heavy duty back zipper closure with pull tab leash for easy self-donning and doffing. Polypropylene is fast drying. The non-buoyant material allows you to maintain your current dive weight requirements. Suit is all black. When worn alone the Skin Suit provides defense against sea lice, jellies, and other irritants along with SPF50 UV sun protection. Unisex suit is available in multiple sizes.
