The O’Neill Hyperfreak Fire 4/3+ Back Zip Full wetsuit is built to extend your time in cold water while maintaining maximum comfort. Constructed with TechnoButter 4 neoprene and ultra-flexible TechnoButter 4X, it delivers a lightweight feel, outstanding stretch, and durability. The internal TB4 Firewall with graphene-infused fibers efficiently retains and distributes heat throughout the body.
Seams are glued and blind-stitched on the inside and sealed with exterior Fluid Seam Weld, minimizing water entry and improving durability. The minimal seam design further enhances flexibility. The 360° Anti Flush Barrier with drainholes prevents cold water from flushing in during wipeouts, while Super Seal wrist and ankle cuffs ensure a secure fit. Reinforced recycled Krypto Armor knee pads protect high-stress areas, extending the lifespan of the wetsuit.
