The Reef Flex Pro is a great all-round wetsuit. The contour cut allows for a better fit with increased movement around the arm and shoulder areas. Made from 100% S-Flex Neoprene rubber lined with G-Flex 7 for flexibility and added warmth. All the seams are GBS for an increased seal. The 4mm Dura-Mesh chest panel increases your protection against wind chill, while the Supra-Tex Knee pads give you greater flexibility and strength on your knee.
