The Bare S-Flex 5mm Wetsuit is a warm and flexible wetsuit with and A-Class thermal rating, better than most other wetsuits in it's category. S-Flex Neoprene is made from a proprietary blend of neoprene which has extreme levels of flexibility and stretch with a soft finish for added comfort.
Where most of it's competitors score a B or C grade the Sport S-Flex scored an A-Class thermal rating for exposure protection, meaning it will keep you warmer than it's competitors. Exposure protection is more than simply thickness of neoprene meaning that this 5mm can feel warmer than some 7mm wetsuits on the market depending on fit and quality.
S-Flex neoprene is incredibly flexible and forgiving compared to traditional neoprene so you have complete freedom of movement in a suit that is much easier to put on. So flexible is the neoprene most divers can still get in the suit one size smaller than their measurements recommend.
