The Furnace Revolution Chest Zip Full Wetsuit is Billabong's thickest Furnace wetsuit, making it the warmest option for colder surf sessions. Lofty fabric is situated around your core to trap heat and keep you on the water longer, while the rest of the suit stretches with ease to allow unrestricted paddling. Meanwhile the classic styling and easy on and off encourage you to turn to this suit again and again.
