Slip into NeoSkin, extremely comfy, like pajamas - You won't want to take it off. Heavier and warmer than Spandex, softer and more flexible than a wetsuit! Completely wind and splash proof. Flexible, smooth interior fabric, makes the Neoskin easy to don and doff. 1mm thick nylon-2 neoprene rubber provides excellent insulation in warm water along with UV protection from the sun's harmful rays and added warmth when used for layering under an exposure suit. When worn alone the Waterproof NeoSkin Suit provides protection in warm water from sun and possible jellyfish stings (or other nasties!). The super stretchy material fits all body shapes and easy donning and doffing is provided by the corrosion-free YKK Vislon rear entry zipper closure equipped with a pull tab leash. When worn under your exposure suit as layering, NeoSkin suit adds warmth by reducing water exchange and makes donning your exposure suit much easier so you won't brake anymore nails when putting on your rubber exposure suit. Skin suit comes equipped with thumb and foot loops (stirrups) so it won't ride up when finning or when donning an exposure suit and the flat lock seam construction is also comfortable to the skin. The thread used is high quality for added strength and durability. This all black NeoSkin suit is available in multiple sizes.
