Providing true freedom of motion paired with supreme warmth, the O'Neill Psycho One Back Zip Wetsuit is a prime example of a high-quality surfing wetsuit. Utilizing the complete coverage of the Z.E.N. closure system and its anti-flush barrier, the Psycho One remains incredibly simple to climb in and out of. The hydrophobic, and soft to the touch, 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.
Dropping the extra panels and shedding all but the best features, the Psycho One boasts insane pliability with the TB3 Neoprene and highly flexible seams. An ultra-flexible and super durable Fluid Seam Weld locks the outside of all the seams from cold leaks and lengthens the overall life of the suit. With a rash resistant collar and interior water barrier, the Psycho One offers comfort, warmth, and durability in a super lightweight, quick-drying suit. Stay warm without feeling smothered in layers of rubber, pull on the Psycho One and step into the water in your second skin.

The Psycho One was recommended by a friend and has not disappointed. It's very warm, dries fast, but best of all the flex in the shoulders for paddling is better than I've ever felt even in other 3/2 wetsuits. Great design for me so far (have been wearing for 1 month now).

Excellent
This will be my third Psycho One...and I love it every time. Flexible, warm, but not too warm:) Use it on the coast for surf and the lake for skiing.

Favorite Wetsuit
Super stretchy, comfy, pretty warm and easy back zip.Best part is I never get neck soreness I get when wearing hooded wetsuits. If I need a hood, I just wear my separate O'Neill hood and it works great.

Great wetsuit
The Psycho One is a very flexible and warm suit. Unfortunately, I'm not as flexible or young as I used to be so I struggle to get into it. Easy to get out of. If it's zipped and sealed correctly, I get no flush even when duck diving. Love it.

Great suit
Super flex, buy smaller Rather than larger, due to the built in flex. Toasty and very comfortable, higher recommend. Surfing Crew Rocks, Excellent Customer Service !
