What Our Gearhead(R) Experts Are Saying: "This suit is warm, super flexible, and easy to get on with the back zip. The 4/3mm thickness gives great insulation, and I can paddle comfortably without feeling restricted. I also love knowing it's made from partially recycled materials-performance with purpose." For early mornings and cold-water lineups, the Billabong 403 Foil BZ GBS Fullsuit keeps us warm, mobile, and ready to ride. Designed with partially recycled Superflex Lite Foam, this 4/3mm wetsuit balances high thermal retention with a lightweight, flexible feel. The Silicone Stretch Recycler interior lining moves effortlessly with the body, providing all-day comfort in chilly surf. Its GBS (glued and blind stitched) seams block out cold water while maintaining the suit's overall stretch, and the easy-entry back zip adds convenience without compromising warmth. Whether you're logging winter waves or paddling out in shoulder-season conditions, the Foil 403 is built to handle it sustainably and reliably.
