Water Temp
The O'Neill Psycho I Zen Zip 3/2 mm wetsuit offers ideal protection in cold waters around 15°C (59°F).
Ultra Minimal Seam Design - Insane flexibility, fit and warmth using a unique design, which utilizes less seams
Single Fluid Seam Weld - Welded seams aim to prevent water from entering at all seams and critical entry points.
Patented Z.E.N. Zip Entry (With Drain Hole) - Featuring a pullover internal neck seal that blocks out water for maximum performance: Any water that penetrates the Z.E.N. Collar or Super Short Zip is blocked by the Barrier and forced out the Drain Hole.
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.
Plasma Seals - Fluid Seam Weld seal at the wrists and ankles prevents over-expansion and locks out water.
Single Superseal Neck - A fully adjustable closure featuring a 360 smooth skin interior, chafe-free unfinished edge, and minimal bulk design.
Lumbar Seamless Design - O'Neill knows that even the best surfers spend significant amounts of time sitting on their boards waiting for waves. By applying a single large panel at the lower back of the wetsuit, water entry is minimized and stretch is maximized.
Barrier 2 - Featuring a pullover internal neck seal that blocks out water for maximum performance in cold to frigid conditions
