Updating my previous review to 5 *****. This suit is a little trickier to get on than the chest zip model, but I find that it keeps you warmer due to less leaking through the neck. The back inner panel does a great job of flushing out the suit. The stretchy TechnoButter 3 neoprene can't be beat. The "sale" price makes it a good value. I would buy it again.

Good suit, tough for an old timer to get on.
Comparing this to my worn out Psycho One Chest Zip, I find the chest zip was easier to get on and about the same to take off. On the back zip model I cannot reach the pullover panel without help, so I fastened a piece of elastic to the neck hole it so I could pull it out and then over my head. Other than that, both suits are very good for all but the coolest periods of Southern Cal surf. Super-flexible TechnoButter is a big plus for both suits. I give this suit four stars and the (unavailable) chest zip five stars.

Order one size larger.
I have a Psycho Tech 43 size XL and it fits fine. 190lbs 5'11". The XL Pyscho One was so small, I could not get it on. Very disappointed. The O'Neill Psycho Tech is the best wet suit I've owned in 60 years.

Highly recommended
Great suit. Very flexible and warm. Easy to get in and out with the back zip.

Awesome Suit
Truly an amazing suit. Sometimes I’ll take it off after a rough morning and the material sitting on my quads will still be dry. I use it for barefooting, and noticed the ankle seals are starting to loosen up from all the spray hitting it. But you’d need pipe clamps if you wanted to avoid that lol
