- O'Neill Psycho I 3/2 Back Zip Wetsuit Awesome Suit-better shop!Review by George George
RatingBefore highlighting the merits of the suit, I just wanted to drop a quick note about Cleanline. I've lived and surfed on Oahu and in North County San Diego, both places at the heart of surf country, and I've never worked with a more professional and compassionate staff. Regardless of where you live, take advantage of this shop, as it is, very simply, the best customer experience I've ever had!(Posted on 7/13/2015) 2015-07-13
Having not bought a 3/2 in about 8 years, I was amazed at the suit's flexibility. Trying it on, it felt, especially around the shoulders, great. In the water, the suit performs, and as I'm landlocked right now, I've been paddling my 6'2" up the Deschutes River, which sits in the mid-50's. The suit is warm, and it performs. In terms of sizing, Cleanline staff pointed me to a MT, which is a perfect fit for my gangly 6'4", 175 pound body.
