This thing has the hydrodynamics of a wet suit with the comfort of a regular full body suit. I have never gone farther underwater than I did with this suit. It is unbelievably repellent not only on the polyurethane but on the fabric as well. Furthermore, the compression and energy return is almost as good as it was advertised. The suit is very comfortable for long races and has little obstruction of movement, unlike the FSPRO. The suit dries extremely quickly- about in five minutes.If this is what 2008's best swimsuit is like, then I can't wait for 2012's fastest swimsuit.
