Boost your heat and your airs with the ultra lightweight Furnace Carbon Comp wetsuit boot. New for the 2019/2020 season, Billabong’s light weight, high-performance neoprene soft sole boot now features Billabong exclusive Furnace Graphene. Innovative new Graphene wrapped yarns combine with carbon fibers for a wetsuit that is lighter, stronger and warmer for longer. Furnace Graphene is 50% lighter than traditional hollow fiber liners and 200x stronger than steel. A Supratex sole offers a barely-there, barefoot board feel.
