The Billabong Furnace Ultra 4/3 Chest Zip Wetsuit is the warmest, lightest, and most high-performance suit in the Billabong line-up thanks to the Graphene + liner, welded and taped seams, and Dry-Max entry system. The Furnace Ultra is eco-friendly too, made of up-cycled car tires. Comfort and warmth are priceless when that winter swell rolls in so be good to our ocean and to yourself in the Billabong Furnace Ultra Wetsuit.

Continuous innovation brings an unparalleled level of heat to the Furnace Ultra. The warmest wetsuit in the world, this is a top-shelf men's wetsuit. It features Billabong's exclusive Furnace Graphene: Innovative new graphene wrapped yarns combined with carbon fibers for a wetsuit that is lighter, stronger and warmer for longer. The pinnacle of wetsuit technology, Furnace Graphene is 50% lighter than traditional hollow fiber liners and 200x stronger than steel. Made from upcycled car tires, the eco-conscious smart foam is topped with Airlite jersey, to radically reduce both weight and wind chill. This incredibly efficient and ultra warm suit is topped with a Drymax entry system to keep water out and heat in. The ultra-lightweight, high stretch and thermal retentive fabrics are combined with 100% externally welded seams and a seamless back panel for the ultimate performance wetsuit. This 4/3mm men's fullsuit features a clean design with small logo hits at the chest, sleeve, leg, and back.
