O'Neill Psycho Tech 4/3+mm Back Zip Wetsuit 2020 in Black

Quick Overview

Brand New Addition For 2020 - The Back Zip PsychoTech!

* Required Fields



The O'Neill Psycho Tech 4/3+mm Back Zip Wetsuit 2020 is a brand new addition to O'Neills range for 2020. This suit brings all of the much loved features of O'Neill's top selling high performance wetsuit, the Psycho Tech and puts it into an easier to get into and no fuss back zip model. With O'Neill's signature Zen-Zip closure - this wetsuit has an extra panel of neoprene behind the zip to prevent that dreaded 'flush' you notice with other wetsuits.

The Psycho Tech + now features an extra 0.5mm of neoprene in both the arms and body making this suit a 4.5mm/3.5mm as well as TBX3 taping on the inside seams to keep it watertight and warmer for longer. The neoprene used in the suit is O'Neill's exclusive TechnoButter3 neoprene which is one of the lightest and most flexible on the market making this suit feel comparable to many 3/2mm suits offered by other brands but much warmer!

This suit is the perfect choice for almost year round use from early Spring through till December.
