By tapping your body’s thermal energy output, the Evoke can insulate your core and keep you warm for hours on end, allowing max comfort on every dive. In fact, lab tests have shown Graphene yields a 5-degree Celsius average temp increase over our original OMNIRED Technology. Fundamentally, Graphene is a one-atom-thick layer of carbon arranged in a hexagonal lattice structure. At room temperature, it’s one of the best conductors of thermal energy ever discovered. Materially, Graphene is strong, flexible, lightweight and, of course, highly conductive—all traits that are well suited for use in a wetsuit.
