Billabong Furnace Ultra 5/4mm Hooded Gullwing Wetsuit
When winter really bites, the Billabong Furnace Ultra 5/4mm is built to keep you in the water for longer.
Designed for the coldest surf sessions, this premium hooded wetsuit combines advanced thermal technology, exceptional stretch and serious water protection to deliver warmth without compromising paddling freedom.
At its core is Billabong's Graphene Ultra Core thermal lining, working alongside Graphene Pro panels through the extremities to help retain body heat where you need it most. The sustainable Ocean+ natural rubber foam construction is paired with recycled Airlite II super-stretch external fabric, creating a lightweight, flexible suit that doesn't hold you back when it's time to paddle.
The Gullwing chest zip entry system makes getting in and out straightforward while helping minimise water flushing, and the integrated hood provides essential protection for your head and neck when the temperature drops.
Finished with externally applied Power Seam liquid-sealed seams and machine-applied Super-flex internal taping, the Furnace Ultra is engineered to keep cold water out and precious warmth in.
Built for proper winter surfing. No compromises.
