The O'Neill Women's Hyperfreak 3/2mm+ Chest Zip Fullsuit Wetsuit is O'Neill's premium cold-transition suit — TechnoButter 4 neoprene and Fluid Seam engineering for serious warmth in a flexible, performance-ready build.

Key Features:

• TechnoButter 4 Firewall — Thermal interior panels at the front, back, thighs, and seat circulate body heat for retained warmth across the entire session.
• F.U.Z.E. Chest Zip Closure — 360° anti-flush barrier with drain holes effectively locks out cold water during duck dives and paddle-outs.
• 3/2mm+ Thickness — Extra 0.5mm warmth bonus over standard 3/2; ideal for fall, spring, and cooler summer sessions.
• Triple Glued & Blindstitched Seams — Exterior Fluid Seam Weld technology delivers a watertight finish throughout the suit.
• Recycled Materials — Eco carbon black-infused neoprene and recycled dope-dyed yarn jersey reduce environmental impact.
• 3D Tapered Wrist & Ankle Seals — Segmented cuff seals minimize flushing for all-session warmth retention.

O'Neill pioneered the wetsuit in 1952, and the Hyperfreak is the apex of that legacy — designed for women who push into cold water without hesitation. The 3/2mm+ keeps you in the lineup when others are getting out.

Sizing: Available in sizes 4–12 including tall options. Refer to O'Neill's women's size chart for chest and height.

Care: Rinse inside-out after every session. Hang on a wide hanger. Avoid direct sunlight, machine washing, and tumble drying.
