Billabong 3 Furnace Comp ST Boot

What Our Gearhead® Experts Are Saying:"I added the 3 Furnace Comp ST Boot to my cold water kit and noticed the difference immediately on a sharply cold morning session. The graphene interior holds heat noticeably well, and the arch strap gets them on and off fast, which matters a lot when you are suiting up in a cold parking lot."Cold water surf has a way of ending sessions through the feet before the body is anywhere near ready to quit. The Billabong 3 Furnace Comp ST Boot is built to close that gap, keeping feet warm and protected through extended cold water sessions without adding bulk or killing the board feel that makes surfing worth doing in the first place.The graphene interior is Billabong's warmest lining material, trapping and retaining heat efficiently across the full foot. Partially recycled SMART foam delivers superior thermal retention in a construction that keeps weight and stiffness low, while PRO STRETCH exterior fabric, built from recycled polyester and elastane, moves naturally with the foot through every turn and maneuver. Fully welded exterior seams seal out water completely without the raised ridges that traditional stitched seams leave behind, and a high-density printed sole provides grip and durability underfoot. The arch strap entry system makes getting in and out quick and easy, even with cold hands, and the Recycler jersey lining, made from partially recycled PET bottles, adds a layer of comfort that holds up session after session.
