O'Neill Psycho One 5/4mm Zen Zip Winter Wetsuit TB3 - 2019

The O'Neill Psycho One 5/4mm back zip wetsuit for winter 2019 has under gone a re-design to now include Technobutter 3 neoprene which is O'Neill's new light weight and ridiculously flexible material. It has completely changed the way the suit feels when on to give you the most comfortable and warm fit ever. TB3 is a total game changer when it comes to wetsuits and when you finally have the pleasure to wear one you will be amazed.

The Zen zip barrier in the back of the wetsuit is designed to minimise water entry whilst draining any water that gets into the back panel rather than the wetsuit.


  • Double Super Seal Neck
  • Single Fluid Seam Weld (Watertight Technology)
  • TechnoButter 3 Neoprene
  • Super Minimal Seam Design
  • Krypto Knee Padz
  • External Key Pocket with Loop
  • Plasma Wrist and Ankle Seals
  • Contortionist Seamless Shoulder
  • Strategic Seamless Paddle Zones
  • Patented Z.E.N. Zip Closure System with Drainhole


Pullover internal seal that blocks out water for maximum performance. Water that penetrates the Z.E.N Collar or Short Zip is blocked by the Barrier-2 and forced out the Drain Hole.


Keeps water from entering at all seams and critical points.


Insane flexibility, fit and warmth using a unique design which utilises fewer seams and giant panels.
