Staff Says Cleanline Staff Matt Says:

"Get this wetsuit and you won't be disappointed. It has been our best selling hooded wetsuit for years, and this year the Psycho Tech 5.5/4 Hooded wetsuit has been upgraded with stitch-less seam technology which is one of the biggest updates we've seen in a while. This means, all internal seams now feature TB3x Tape giving the suit an even more watertight, and durable seam. On top of this, you get all the usual features of the Psycho Tech like the super stretchy hydrophobic TB3 neoprene, and one of the best and most watertight zipper/entry systems in the industry. O'Neill is always a good choice and this year is no different when it comes to their flagship wetsuit."

The O'Neill Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit is one of our top selling wetsuits. It's made with buttery soft TechnoButter 3 neoprene and 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, a F.U.Z.E. (Front Upper Zip Entry) closure, and a urethane coated zipper with offset teeth as an anti-flushing barrier. 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 Psycho Tech.
