The O'Neill HyperFreak 3/2mm+ Chest Zip Fullsuit is built on O'Neill's flagship F.U.Z.E. platform with an extra 0.5mm of warmth — making it the ideal suit for mid-season to early winter sessions when a standard 3/2 isn't quite enough and a 4/3 is too much.

The PLUS (+) designation means you get 0.5mm more neoprene across the core, pushing the warmth window into the 58–65°F range. Built from Recycled TechnoButter 3 and TB3X neoprene — 90% or more recycled fibers in the liner fabrics — high performance with a reduced environmental footprint.

• F.U.Z.E. Closure (Front Upper Zip Entry) — chest zip seals cold water out during duck dives and paddle-outs; no cold flush down the spine
• Recycled TechnoButter 3 (Full Body/Legs) — O'Neill's lightest eco neoprene with exceptional flex and near-zero water absorption
• Recycled TechnoButter 3X (Arms/Shoulders) — pre-stretched TB3X delivers maximum stretch where your paddle stroke demands it most
• PLUS (+) 0.5mm Extra Thickness — extra warmth layer over standard 3/2 for sessions in the mid-50s to low 60s
• TB3X Fully Taped Seams — glued and blindstitched seam tape for a waterproof finish at every panel join
• 360° Barrier with Drain Holes — anti-flush barrier keeps water out; drain holes let it exit quickly
• Seamless Paddle Zones — zero seams through the shoulder and arm panels for unrestricted range of motion
• Aqua Alpha Solvent-Free Neoprene Lamination — eco-conscious adhesive with strong bonding performance

Sizing: Men's sizes S–XXL including tall variants. Refer to O'Neill's size chart using chest and height for best fit.

Care: Rinse in fresh water inside and out after every session. Hang inside-out away from direct sunlight and heat. Do not machine wash or tumble dry.
