The O’Neill Hyperfreak Fire 5/4+ Chest Zip Full wetsuit is built to handle the challenges of cold-water surfing. Made with TechnoButter 4 and TechnoButter 4X neoprene, it provides lightweight performance, flexibility, and durability without restricting your movement. The latest generation of TB4 Firewall, reinforced with graphene fibers, traps and recirculates heat more efficiently across the body, extending your time in the water.
Sealed with glued and blindstitched seams on the inside and exterior Fluid Seam Weld, the wetsuit minimizes water entry while maintaining flexibility thanks to its minimal seam design. The 360° Anti Flush Barrier with drainholes, combined with Super Seal wrist and ankle cuffs, prevents sudden flushing from cold water. Recycled Krypto Armor knee pads protect high-stress areas, increasing the wetsuit’s durability and lifespan.
