Wasn't sure, but glad I bought it now., 6th Sep 2016

Reviewer: Doran Welch

Was in the Gorge for the summer and my 3/2 wasn't really cutting it in terms of warmth, especially when foiling where I dreaded trying anything new and going in head first and getting cold again. Decided to buy a 4/3mm and was looking at the standard model, but the guy at Windance convinced me the Psycho was a much better suit and worth the extra money. Glad he did, because it was like night and day. The suit is warm and let's very little water in. Super stretchy so it has a nice fit, excellent neck seem, lightweight for a 4/3, and it really does dry faster. It's a little more effort to get in and out of, but worth it for the benefits. The suit has vents on the arm and leg seems to let out water, and they work well, but if it's really ripping and I get a strong water jet off the board, it will fold over and trap the water on the legs - but you get this on any full length suit and my ankles are a little on the smaller side, so the fit isn't that tight. A pair of velcro straps will fix that. So in short, very happy with the suit.
