The O'Neill Psycho Tech 4/3 Hooded Wetsuit is the new generation of our shop favorite, the Pyrotech. This premium coldwater suit has the warmth, flexibility and durability you want in a wetsuit and is constructed with high quality materials from one of the greatest innovators in the industry. Made from 100% TB2 Neoprene, the Psycho Tech is super stretchy, lightweight, soft and pliable. TB2 truly is a step ahead of the game when it comes to quality neoprene. It is the most advanced super stretch neoprene available on the market. 20% lighter, 30% less water absorption, with improved durability and quick dry properties, you just can't beat it.
O'Neill's F.U.Z.E. system allows for an easy in and out chest zip design while still sealing up nicely to provide a snug fit and prevent flushing in all directions. With the insulating TechnoButter 2-Air Firewall Neoprene in the chest and back panel and the Single Fluid Seam Welds you don't have to worry about getting cold. The Psycho Tech provides all the warmth you'll need so you can comfortably surf anything from 50°F water and up.
O'Neill delivers an amazing coldwater suit that offers lightweight protection from the elements, unrestricted flexibility and superior warmth. What are you waiting for? When it comes to a hooded wetsuit, look no further than the Psycho Tech.

- O'Neill Psycho Tech 4/3 Hooded Chest Zip Wetsuit Awesome Suit and Great Customer ServiceReview by Nrcruit Nrcruit
RatingHad a bunch of questions about this suit before the purchase and the guys on the website chat helped me narrow down exactly what I needed. Suit got to me quickly and it's amazing. I'm 6'1" and 190lbs and the suit fit perfectly. Was not the biggest fan of the built in hood before purchasing this suit but I love it now. The O'Neill hoods are a little lighter than other ones I've had in the past so it does not feel restrictive at all. Super easy to pull off the hood if you get hot too, you don't really notice it.(Posted on 5/16/2016) 2016-05-16

- O'Neill Psycho Tech 4/3 Hooded Chest Zip Wetsuit Fit and Finish - Top NotchReview by Surly1 Surly1
RatingI am 5'11" and 165 lbs, wearing a size - Medium. The fit is ideal and comfortable due to the TB2 neoprene. It is nice and stretchy even in a 4/3, giving you warmth and range of movement. I surf the west coast but mainly Oregon and this suit is plenty warm even on a 36 degree air temp and 50 degree water temp winter morning.(Posted on 1/14/2016) 2016-01-14
In addition, I can't say enough of the crew at Cleanline. They are awesome! Over the past few years I have purchased numerous items plus, 2 suits for my daughter, a wetsuit for my wife and a longboard for her. Each interaction, whether in store or online, has been exactly the same. They treat you like a King. They even took in my daughters outgrown wetsuit on trade and gave us credit toward a new one. Lastly, I have found fun little surprises packed into my orders - hand written notes, wax, candy, reef calendar etc... Its just like when they used to put prizes in your cereal box. Thanks for the great service, you rock!

RatingI surf in Northern California and this has been my go to suit for a few years now. It's warm enough for the winter, but still not too hot in the summer. Perfect if you're only going to have one suit.(Posted on 10/19/2015) 2015-10-19
