Matt Says:

"The Psycho Tech 5.5/4 has been our best selling suit for 3+ years straight, and for good reason. O’Neill has really taken the time to do the research and make the most high performance coldwater hooded wetsuit out there. Recently they released their new TB3 Neoprene, which is the biggest update you’ll see in the PsychoTech. Other than being lighter, and more flexible, it’s still the most watertight, easy to get into, high performance wetsuit out there for water temps from the low 50’s down into the 40’s. "

Details

The latest and greatest version of the O'Neill Psycho Tech 5.5/4 Hooded Wetsuit is the same suit we all love, now fitted with Technobutter 3 Neoprene. Keeping a nearly identical design, the Hooded Psycho Tech was built to combat the rigors of hours spent paddling in cold temperatures. Including the most advanced heat trapping elements, the Psycho Tech has external fluid seam welds, internal taping in critical areas and quick drying TechnoButter Air Firewall Smoothskin panels in the chest and back to block wind chill and soak up the sun's warmth.

TB3 (TechnoButter 3) neoprene incorporates O'Neill's exclusive feather-lite ENVY foam core, creating one of the lightest and most flexible wetsuit components to date. The hydrophobic TB3 is strategically placed in the shoulders and extremities giving you maximum maneuverability where you need it, while TechnoButter Firewall Neoprene cushions the thighs and waist. This tactical combination of materials and seams delivers both long term durability and a snug, comfortable fit.

Focusing on a pleasant and productive experience in coldwater conditions the Psycho Tech ensures you get all the features you need without any of the extra bells and whistles. Wrist and ankle seals, durable knee pads, heavy duty zippers are all part of the package along with a toasty warm two-layer F.U.Z.E chest zip that keeps water from entering at critical points and seams while retaining a relatively generous entry. Offering the best bang for your buck, the O'Neill Psycho Tech is simply a high quality, high-performance surfing wetsuit.

O'Neill Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit Light and flexyReview by Steinarr Steinarr

As a surfer in Iceland for 25 years I can say with confidence that this is the best. The material is a real break through. it´s super stretchy and light. Thick wetsuits will wear you down if you surf 5 time a week for 4 hours each session. This one doesn´t. Buy it!

O'Neill Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit Flex!!!Review by Chris D Chris D

First off, the Cleanline team is beyond awesome! Figured out my size over the phone, got some recommendations based on my location (NJ), and threw in some extra goodies with my package!

I was just able to try out the suit itself for the first time earlier today - the water was right around 38-39* and I was in for a solid hour and a half. When I first tried it on, it felt like I was wearing a 3/2 getting ready for a summer swell! I love the fit, flex, and weightlessness of the thing. I did drop down from a 6/5 that I've worn the past few winters so I'll admit I wasn't quite as warm, but the suit did exactly as described by warming up with every movement I made - and the weight/flex gave me that extra energy to keep paddling around where I used to be absolutely dead after a paddle-out! Excited to see how this holds up through the colder air temps the rest of the winter, but I'm a believer now!! O'neill's got it going!

For reference, I'm 6'0, 170lbs with a bigger chest and the MT fits perfect...

O'Neill Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit Great wetsuit!Review by Elkappyton Elkappyton

This is my first thicket wetsuit so I have nothing to compare it to, but it seems to work great. I get cold pretty easy and am able to stay out 2+ hours in water temps around 38 degrees. The suit doesn’t get too much water in it unless you’re really getting thrown around. Also, I have zero problem paddling or moving around; it feels similar to my lower end O’Neill 3mm. All in all great suit and no complaints!

The suit is great, the best I’ve ever had so light and warm it’s insane feels like half the weight of my old O’Neill suit. But really Cleanline is the winner here. This shop not only shipped my suit for free and had it to me in 2 days they sent a post card thanking me for my purchase and personally writing in description of what I bought and hoping I enjoy it. I have to say that customer service is really nice. I love this place they have a customer for life.

Had a nice Excel for about 7 years. Just called it quits in my hotline, I had for another 7. This is the Cadilac of suits. You can move any place you want no struggle. This thing keeps water out very very well. It was between this and the nice rip curl, this one fit me better as I’m 6’ solid buck 80. Little bit taller inseam and longer arms I noticed compared to the high end rip curl. Went to the usual cape lookout in some heavier conditions twice now and I’m so impressed. Closest to no wetsuit you can find, doing laps around my mates! All bs aside it’s a great suit, I get out maybe 50 times per year so I should get about 2-3 years I’m hoping with this tech. Thanks again CLSS.

Went out today ( early January) using the 5.5/4. Generally I stay pretty warm anyways and this suit was so warm I could easily have had a thinner wetsuit. If you feel the cold and want a really warm suit that was pretty easy to get off (even with those tired, after surf shoulders) this suit is for you. I wore slightly thin booties, which at the end of my surf got a little chilled but my body didnt get cold at all and I stayed out for almost 3 hours.

I'm 6'1" @ 183 naked, and dig the size LT. I thought my last O'neill was awesome, but this one is even better. For a 5.5 mil suit it is super stretchy. The form fitting cut doesn't stifle paddling even on the longest sessions. The inside material doesn't grip to your skin so it's super easy to slide in and out of, dry or wet. Just about all of the high end wetsuits are really good now, but if you are looking for a high performance suit that works great for surfing a few times a week, go with an O'neill.

O'Neill Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit All Performance No Frills Review by Cam Cam

This suit just works, it keeps you plenty warm even on the coldest NW days. I've worn almost all major wetsuit brands 5/4's and this is the best suit I have owned yet. The quality of this suits construction is hands down the best out there which I have seen. When I compare side by side my Xcel Drylock 5/4 you can see quality differences in the seams (and Xcel is no slouch). Suit drys quick and is flexible for a 5/4. What else do you need? Also, I had an older version of this suit (2015) and noticeable improvements have been made in regard to wetsuit material.

Only downfall to this suit is the hood, the visor is abnormally large and goofy looking so I just trimmed mine down with scissors.

So I've worn pretty much all of the major supplier's wetsuits available and obviously, everyone has their own opinions, likes, and dislikes. These are strictly my opinions so of course take all I say with a grain of salt. I've been wearing wetsuits for about 45 years now in the cold waters of the northwest ( northern Oregon where the Columbia river meets the Pacific Ocean). I've been wearing Patagonia wetsuits for the last three years and Ripcurl for three or four years previous. Before that was O'Neill and for many years Hotline was the choice for me.I only have allegiance to the best. I wear what I think is the best because my wetsuit is my most important tool. All this said I recently grabbed an O'Neill Psychotech off the rack because I kept hearing and listening to all the hype on the phone and in the shop. Paavo, my manager (awesome surfer, incredible guy)keeps telling me (and customers) what a killer wetsuit this is, and I really respect his opinion. Definitely O'Neill's flagship and best wetsuit ever! Wow big statement! So here is what I found, great, super soft, flexible and just buttery (Techno rubber) Neoprene. In the water the suit is unbelievably water tight. I couldn't believe how dry I stayed for a 2 and a half hour sesh. Also it's really REALLY warm. While sitting on my board between sets I could feel the sun baking the firewall interior lining like it was an electric vest! This is one GREAT wetsuit!
