O'NEILL HYPERFREAK FIRE 4/3+MM BACK ZIP FULL WETSUIT - BLACK/BLACK (5663)

The O'Neill Hyperfreak Fire 4/3mm+ Back Zip Full Wetsuit is O'Neill's premium cold-water suit, built with next-gen TB4 Firewall neoprene featuring graphene-infused, heat-retaining, durable fibers. The "+" means an extra 0.5mm of thickness for added warmth, while a strategic panel layout of TechnoButter 4 and ultra-stretch TechnoButter 4X keeps the suit light, flexible, and fast-drying.

Exterior Fluid Seam Welds over triple glued and blindstitched seams, Fused Super Seal cuffs, and the patented Z.E.N. back-zip closure with anti-flush barrier lock out cold water so you can stay out longer through fall and winter sessions.
