Psycho
"I’m very happy with the fit and performance of this suit. I am 6’1” 225 with an athletic build. Initially it was a bit of a tight squeeze in my shoulders but with a couple of adjustments the suit fits great and allows for plenty of mobility"

Great for NE Winter.
"Im 5’11 180lbs, Large fit perfect. Pretty warm suit. Was able to stretch throughout Maine winter for about 1-2 hours. After 2 hours I started to get cold. Would buy again."
Most comfortable cold water suit I’ve found yet
"I have tried a lot of different 5/4 suits and this one is definitely the most comfortable suit I’ve had yet. Super stretchy and pretty warm as well. My rip curl 5/4 is a tad warmer but the O’Neill crushes it in comfort. It isn’t bomb proof on durability but it did last me 150 days on the river. I’ll be ordering a freshly on spring. Cheers"
Great wetsuit,kept me warm the
"Great wetsuit,kept me warm the whole time thank you."
So far, so good
"I purchased this suit to replace a 3 year old 5/4 mm Mutant. Am 5'7" and 140 lbs and the MS length is perfect but the shoulders are a bit tight as is the hood. The suit is well constructed and keeps things warm so far. Have been wing foiling in 40F water and 20F air temps in Rhode Island without problem, hopefully it holds up when the water and air temps drop further. The internal lining is great, but there are some thin strands of insulation that seem to be popping out. Not a big deal at this time. Overall, a solid suit for the colder winter months."
Awesome wetsuit
"I’m in NJ and so far I’ve been warm and even dry. Most days I’m sweating in all my gear. Suit is obviously thick but flexibility is great. Best wetsuits in my opinion are O’Neill and rip curl."
