Have you ever seen surfers out for a rip, only to dip your toes in quickly and exclaim, "Woah, these guys are psycho!" Well they are, except their madness can largely be explained by the fact that they're probably wearing the O'Neill 4/3 Psycho One F.U.Z.E. Wetsuit. Constructed from a super stretchy, movement-friendly TechnoButter 2 Neoprene with strategically placed seamless paddle zones, the 4/3 Psycho One Wetsuit is so comfortable that you'll probably end up wanting to wear it out on Friday night. Join the league of wave-crazed psychos and paddle out in the O'Neill 4/3 Psycho One F.U.Z.E. Wetsuit.
TechnoButter 2 Neoprene – O'Neills most advanced neoprene to date. All while reducing the material's weight, TechnoButter offers superb stretch, minimal water absorption, quick-dry properties, and long-lasting durability.
F.U.Z.E. Entry Closure System w/ Drainhole – Uses the same zipper technology as O'Neill's Z.E.N. zip closure and features their ultra-dry 3x water drain system that keeps you dry without restricting flexibility. Water that penetrates the F.U.Z.E. Collar is blocked by the Barrier-2 and forced out the drainhole.
10-15°C (50-59°F)
Strategic Seamless Paddle Zones – Ergonomic seamless undersleeve panels that allow for unrestricted motion and prevents rash.
Double Super Seal Neck – A warm, chafe-free and comfortable two-layer design featuring Smooth Skin interior lining. O'Neill's Superseal is fully adjustable and securely locks out water.
Krypto Knee Padz – The knee pads are abrasion resistant and made of high-stretch neoprene. The panel has an ergonomic shaping designed to extend the life of the wetsuit and protect your knees.
Super Minimal Seam Design
External Key Pocket with Loop
Plasma Wrist and Ankle Seals – Having seals at entry locations helps trap in the warm water and block out the cold water.
Contortionist Seamless Shoulder – Fewer seams for warmth, and improved mobility.
