I wore this suit three times this fall-into-winter of 2010. It is in pretty great shape, just a little too much room around the chest area for me. Seals on the arms/legs/neck/ and hood fit is solid. Just don't have the chest for it, ha.
The 5/3mm Hurley Fusion is a nice, stretchy cold-water choice. The suit is made of 100% superstretch neoprene for maximum flexibility without added bulk. The sealed & taped seams work together with the waterproof chest zipper to keep cold water from trickling in while the poly fleece lining wicks moisture from the skin. The attached hood is also lined with poly fleece for some added warmth.
