The O'Neill Pyscho Tech is one of our top selling wetsuits so we were excited when O'Neill added 0.5mm of extra neoprene in this already hi-tech wetsuit. Made with buttery-soft TechnoButter 3 neoprene the O'Neill Psycho Tech 3/2+ Back Zip Wetsuit will keep you toasty warm with its heat-generating TechnoButter Air-Firewall insulating interior jersey. To ensure water stays out it has super seal cuffs, the Z.E.N. (zip entry system) closure, and a urethane coated zipper with offset teeth that act as anti-flushing barriers. Best of all it was constructed using a stitchless seam technology and a fluid seam weld to keep water out. Stay warm and toasty in any condition with the Pyscho Tech Plus.
