Proud to say that I was competitive in my Drylock and felt it gave me an advantage over other surfers. This suit not only keeps you warm, it feels like butter. The fact that I could full twist without restriction and paddle without pulling in my arms was a real benefit. Swimming is hard when you are tired and wetsuits can be exhausting and finally I felt free of that. I came in second place and I am going for it. This suit is for serious surfers who want to extend sessions and push their limits.
