About O'Neill 4/3mm Heat Men's Back Zip Full Wetsuit
Lightweight Warmth for High-Performance Sessions
Built for demanding surf sessions and cold-water performance, this 4/3mm back zip wetsuit combines premium insulation with lightweight flexibility. Exclusive TechnoButter 3 neoprene is 20% lighter and absorbs 30% less water than conventional premium neoprene, helping reduce weight while maintaining exceptional comfort throughout your session. TechnoButter 3 Firewall panels in the chest and back further enhance warmth and flexibility for unrestricted movement in cooler conditions.
Engineered for Comfort and Flexibility
The redesigned 3Q back zip entry makes getting in and out of the wetsuit quick and easy, while the Redzone water-resistant zipper helps minimize water entry. A Double Super Seal Neck improves comfort around the collar, and Seamless Paddle Zones maximize mobility where it's needed most, allowing natural arm movement during paddling without unnecessary restriction.
Advanced Construction for Lasting Performance
Fluid Seam Weld construction reinforces the seams for enhanced durability and water resistance, while Wind-Proof Smoothskin panels help reduce wind chill during surface intervals. An external key pocket with an integrated loop keeps small essentials secure, and Aqua Alpha solvent-free lamination reflects O'Neill's environmentally conscious manufacturing approach. Combining premium materials with advanced construction, this men's wetsuit is built for warmth, flexibility, and dependable performance.
