I bought this suit just a few months ago and have surfed in it about 4 times and was very stoked on the fit and flexibility. Last weekend I drove seven hours for a surfing weekend in Washington State. I went to put on my suit and low and behold, as I went to zip it up the zipper popped a tooth and separated the two sides. After much struggling to get the two sides together (older zippers are metal so you can separate the zip then clamp down around the teeth - not so with newer zippers since they're plastic. Needless to say, I was super bummed. I had the foresight to bring my backup suit (O'neill Epic 4/3) which is 17 years old!). I did get to surf all weekend in my older suit, but I could've remained in the water much longer in the 5/4/3.
