The RB1 was designed to provide surfers with the ultimate combination of warmth and flexibility. It features a chest zip entry for easy access, with ultra-span flex fabric lining both the interior and exterior, enhancing stretch and comfort. The seams are triple glued and blind stitched for durability, while the external fluid seam weld prevents water from entering. S-seal waterway seals at the wrists and ankles further improve water resistance, and internal seam tape reinforces key stress points. Made from a special blend of neoprene, the RB1 also includes embossed Supratex Tuff kneepads for added protection and durability. A convenient key pocket adds to the practicality, making the RB1 a top choice for surfers seeking high performance.
