The Psychotech from O'neill is definitely one of the key leaders in today's wet suit technology and my experience with the Psychotech has been nothing but positive. The Techno Butter 2 neoprene (TB2) incorporated into this suit has an increased stretch which leads towards more mobility and comfort. In my opinion one of the most attractive aspects about the TB2 is the fact that it absorbs about 30% less water which keeps the suit lighter, more comfortable when surfing for long periods of time and allows the suit to dry faster. Another important piece to this suit is the fully welded seems on the outside, as well as welding placed in the critical areas on the inside. This will also decrease the amount of water entering the suit through the seams, essentially keeping you warmer and more comfortable. This is my suit of choice for cold water surfing. Fit is great, the comfort and warmth is unbelievable and the wet suit technology is unbeatable!
