2026 O'Neill Hyper Fire X Chest Zip 4/3 Wetsuit

2026 O'Neill Hyper Fire X Chest Zip 4/3 Wetsuit

The HyperFire X is O'Neill's flagship winter steamer — their best materials, best seam construction, and best thermal tech in one suit. Built for serious cold-water surfing, the 4/3mm chest zip configuration keeps warmth in and water out across the full session. The FUZE chest zip entry makes getting in and out fast, with an anti-flush barrier and drain holes that seal effectively without the bulk of a back zip.

Key Features

• TB4X Superstretch Upper Body: Maximum freedom of movement through the shoulders and arms — paddles without restriction, easy entry and exit.
• TB4 Air Firewall Chest & Back Panels: Air-pocket insulation reduces thermal heat loss across the core — the warmest panels in the O'Neill lineup.
• Graphene-Infused Fire Wall Lining: Internal lining keeps you dryer and warmer, touch-dry in 30 minutes after hanging.
• Fluid Weld Seal Seams: Double-sealed externally with internal critical taping — minimal seam design reduces cold-water entry points.
• Double Seal Collar: Keeps water out at the neck without choking — a detail that matters on longer sessions in cold conditions.
• FUZE Chest Zip System: Anti-flush barrier with drain holes for an effective seal — easy in and out without compromising warmth.
• O'Neill Blue Sustainable Materials: Limestone neoprene, recycled oyster shells, car tyres and plastics, solvent-free lamination, and dope-dyed yarn — built with the ocean in mind.
• External Key Pocket: Secure loop-closure key pocket — standard on the HyperFire X.
