2026 O'Neill Men's HyperFreak 4/3+ Steamer Back Zip - Black

2026 O'Neill Men's HyperFreak 4/3+ Steamer Back Zip — Black

The HyperFreak is O'Neill's most flexible cold-water steamer — built for surfers who want maximum stretch and minimum bulk. TB3X neoprene through the upper body delivers unrestricted paddle movement, while the minimal seam design keeps the suit light and the water out. The back zip entry makes it fast to get in and out, and the 4/3+ thickness handles Australian winter conditions without overheating on the paddle.

Key Features

• TB3X & TB3 Neoprene: TB3X pre-stretched neoprene through the upper body for maximum paddle freedom — TB3 through the lower body for core warmth and durability.
• 4/3+ Minimal Seam Design: Fewer seams means more stretch and less water entry — unrestricted movement through every turn and duck dive.
• GBS & Taped Seams: Glued and blindstitched construction with internal critical taping — watertight without sacrificing flex.
• Krypto Knee Padz: High-stretch, abrasion-resistant knee pads that mould to the joint — board protection and comfort during heavy sessions.
• Double Seal Collar: Smooth adjustable neck seal — stops cold-water flushes and neck rub on longer sessions.
• Back Zip Entry: Fast in and out — straightforward entry system for everyday use.
• O'Neill Blue Sustainable Materials: Recycled yarns, solvent-free lamination, and neoprene from recycled tyres and oyster shells.
