O'Neill Psycho Freak 5/4mm Chest Zip Wetsuit

The ultimate in wetsuit technology. Redesigned for 2017, the Psycho Freak gains additional heat retaining TB Firewall, and the lightest, driest neoprene ever: TechnoButter 3.

Suit up with confidence in premium technology evolved from over 60 years of cold-water R&D experience.

  • RedZone water resistant Zipper
  • 360° Barrier with Drainholes (F.U.Z.E)
  • 20% TB3
  • 20% TB Air-Firewall Smoothskin
  • 60% TB Firewall

TechnoButter 3 - Exterior Jersey:

To create the best stretching, durable, soft and hydrophobic material, we chose the finest technical yarns with permanent water resistant properties. Tough enough to withstand our rigorous testing standards, TechnoButter 3 stretches like crazy and has a buttery soft feel.

TB3X - Interior Jersey:

The X-Factor makes this the lightest, most stretchy neoprene ever. An exclusive form of Tb3 is "pre-stretched" pulling the jersey just far enough to break the fibres apart but still hold it's structure for maximum flexibility.

TB3X also increased warmth with a low profile that sheds water while drying ultra fast. This new weightless tech feels so soft against your skin you'll swear you were surfing naked.

F.U.Z.E Entry Closure System:

Uses the same zipper technology as our Patented Z.E.N Zip Closure keeping you dry without restricting flexibilty.

TB-Air Firewall Smoothskin:

The most advanced insulative neoprene available. Trapped air technology with quick dry properties. Psychotically warm.

Super Seal Handcuffs:

Buttery soft premium neoprene stretches like crazy. Technical yarns and a revolutionary foam rubber core make it light & durable with quick-dry properties.

Super Seam Weld:

Stitchless, 4mm silcone-based urethane seal applied to both the sides of a triple-glued seam. Lightweight, non-chafing, waterproof and flexibile.
