O'Neill Men's Psycho Tech 4/3+mm Chest Zip Full Wetsuit

Master the cold with the ultimate "Liquid Flow" powerhouse. The O'Neill Psycho Tech 4/3+ is engineered for riders who demand elite warmth without sacrificing the freedom of movement needed for high-performance wake sessions.

Built for Performance and Longevity:

• TechnoButter 4 (TB4) Firewall: The most advanced neoprene in the game, infused with recycled graphene to trap heat and keep you in the water longer.
• The "Plus" Advantage: This isn't a standard 4/3. The 4/3+ construction adds an extra 0.5mm of thickness (4.5mm body / 3.5mm limbs) for a massive thermal boost.
• Stitchless Exterior Fluid Seam Weld: 100% sealed and glueless exterior seams that are more durable and flexible than traditional stitching.
• Duraskin Air Firewall: Wind-proof smoothskin panels on the chest and back shield you from the biting wind chill experienced behind the boat.
• F.U.Z.E. Closure: O'Neill's exclusive Front Upper Zip Entry keeps you dry and allows for unrestricted mobility.

Sustainable Tech: Built with recycled oyster shells, eco-carbon black, and solvent-free lamination.
