O'Neill Mens Psycho Tech Hooded Chest Zip Steamer Wetsuit 5/4mm

O'Neill Mens Psycho Tech Hooded Chest Zip Steamer Wetsuit 5/4mm combines O'Neill's TechnoButter 3 neoprene and added heat-generating TechnoButter Air-Firewall. The Psycho Tech comes equipped with top tier technology features you need to stay warm and toasty in any condition. 

O'Neill's insanely stretchy TB3 Neoprene delivers the greatest elasticity of any technical neoprene thanks to the Envy Foam core rubber which effectively insulates by maximising cell volume without increasing the chance of cell wall failure (cell wall failure basically turns your wetsuit from foam into a sponge).

The Psycho steamer features a fluid seam weld is an 8mm silicone-based urethane sealed exterior with a triple-glued and blind stitched interior. It runs along the inside of the wetsuits seams for added sealing and durability, Providing you with maximum stretch in a non-stiched design. Learn more about seams here. 

Aqua alpha solvent-free lamination is an extremely strong water-based, non-toxic, and solvent-free lamination glue that O'Neill uses to laminate the inside and outside lining to the neoprene.

To get the most out of your O'Neill Men's Psycho Tech Hooded Chest Zip Steamer we recommend washing it with Wetsuit Wash & reading our maintenance guide.
