The O’Neill Hyperfreak Fire 3/2+ Chest Zip Full is made for spring, autumn, and cooler summer conditions when water temperatures call for lightweight warmth and maximum flexibility. TechnoButter 4 and TechnoButter 4X neoprene provide stretch and comfort, while the TB4 Firewall with graphene-infused fibers helps retain and distribute heat for consistent performance.
Sealed with glued and blindstitched seams plus exterior Fluid Seam Weld, the suit minimizes water entry while the minimal seam design improves flexibility. The 360° Anti Flush Barrier with drainholes and the Double Super-Seal Collar prevent sudden flushing, keeping you comfortable longer. Recycled Krypto Armor knee pads reinforce durability in high-wear zones, while a key pocket with loop adds everyday practicality.
