O’Neill Hyperfreak Fire 3/2+ Back Zip Wetsuit – Next-Gen Warmth and Flexibility
The O’Neill Hyperfreak Fire 3/2+ Back Zip Full Wetsuit pushes cold-water performance to the next level with graphene-infused TechnoButter 4 Firewall neoprene — O’Neill’s most advanced, heat-retaining material ever. Designed to extend sessions in frigid water, it combines superior warmth, stretch, and durability in a lightweight, eco-friendly package.
The TB4 Firewall’s recycled graphene fibers create a “fire-hot feedback loop” — as your body warms the suit, it conducts heat back toward your skin for unmatched insulation. Meanwhile, Fluid Seam Welds, Triple Glued and Blindstitched construction, and Fused Super Seal Cuffs ensure a watertight, flexible seal that keeps the cold out and comfort in.
