    The most flexible and lightest of the cold water suits. Easy entry and suit removal due to the flexibility of their rubber. Excellent everyday suit.

  2. Technobutter is Sick!

    This Wetsuit is by far the best 4/3 wetsuit I have ever used. Technobutter technology is incredibly flexible. I now own the O'Neill Pyrotech 3/2 and 4/3 hooded. I gave the 4/3 4 stars out of 5 because the chest was a little tight on first wearing and the hood was a little high on my forehead. These two things did not effect my surf session what so ever and probably will loosen a little after a few wearings. and adjustments. No regrets on purchase. I am 6'0" 180 pounds and ordered a Large. No regrets on size although the 4/3 hooded was a little more snug than the 3/2 which was expected. Again, the Technobutter technology is by far the most flexible and warmest 4/3 suit I have used. My previous 4/3 suit was an O'Neill Mutant. Another great suit, but not as flexible as Pyrotech. Enjoy, get out and surf!!
