Introducing a major innovation in wetsuit comfort; Reactive, the first wetsuit in dive to use Graphene OMNIRED Infrared fabric, a responsive textile, that continuously warms the diver using their own body heat. The suit is made with scientifically proven OMNIRED Infrared Technology - 13 thermo-reactive minerals woven into the fabric lining that convert body heat into infrared energy and reflect it back onto the diver. The body-responsive effects of Graphene, combined with the power of OMNIRED, allow divers to maximize their comfort on every dive. Medical studies have shown that infrared energy improves the body's circulation. Increased circulation improves oxygen levels in the body, enabling you to use less energy, improving overall warmth, and increasing your dive time. OMNIRED Infrared Technology helps conserve lost body heat and accelerate thermal recovery. Keeps you diving longer and recovering faster. The first dive wetsuit made without a single seam stitch, Reactive uses Bare's patented No Stitch Technology (NST). NST isolates the body from the water eliminating seam leakage using taped seams inside and out. Using the power of OMNIRED Infrared Technology to insulate the body, combined with NST, this creates the world's warmest dive wetsuit. The Bare 3mm Reactive Full Suits are made from Elastic Full-Stretch nylon-2 neoprene combined with OMNIRED fabric for Bare's highest degree of warmth, stretch, and comfort. The Reactive Full Suit has a hook and loop adjustment on collar features a booklet-style cover, to protect your suit from snags and pilling and seamless underarms for superior comfort and mobility. Fundamentally, Graphene is a one-atom-thick layer of carbon arranged in a hexagonal lattice structure. At room temperature, itfs one of the best conductors of thermal energy ever discovered. Materially, Graphene is strong, flexible, lightweight, and, of course, highly conductivefall traits that are well suited for use in a wetsuit. Extra-long 21" (53.3 cm) S-Lock2 back zipper with offset tooth design. Polyurethane (PU) coated zipper tape guards against water entry and skin-to-skin double internal sealing zipper flap for added warmth. For easy donning and doffing the zipper is equipped with a full-length puller with silicone print for easy grip and a grip tab at the base of the zipper to further increase the ease of self-fastening the zipper. Armor Flex 2.0 highly flexible, durable, abrasion-resistant 3-D kneepads; help protect this high-wear area. The suit is built to fit right with an anatomically correct pattern for three-dimensional fit throughout. The suits seams are glued and taped for strength and durability. The suit is available in multiple sizes and colors.
