Continuous innovation brings an unparalleled level of heat to the Furnace Ultra. Our warmest high-performance hood ever, the Furnace Ultra now features Billabong exclusive Furnace Graphene. Innovative new Graphene wrapped yarns combine with carbon fibres for a wetsuit that is lighter, stronger and warmer for longer. The pinnacle of wetsuit technology, Furnace Graphene is 50% lighter than traditional hollow fibre liners and 200x stronger than steel. A face opening shape that allows for greater peripheral vision is combined with a stretch panel at the centre back, offering greater visibility all around.
