Yep. I have to say that Technobutter Neoprene is the by far the best thing I have seen from the wetsuit industry this year. I’m waiting for this suit(or the Psycho 3) to win wetsuit of the year. It’s funny because I haven’t heard a lot of hype behind it, but it’s awesome. For the past few weeks I have been wearing the Fall 2013 Pyrotech 5.5/4 Hooded Wetsuit, and it honestly is so lightweight and flexible it feels like a 4/3. Being a tall and lean guy(5’11″ 157lbs) I fit the O’Neill suits perfect. I’m wearing a size small because this thing is that flexible. It pretty much feels like a second skin, and is extremely comfortable.
