I want to thank all of you for your quick response and suggestions. Just to elaborate on a couple of points that were brought up. My wife is not in the 1% body fat catagory, although I thinks she remembers a time long ago when that was the case. She just gets cold easily even in summer. There is no 80 degree water in the NW that I know of except in the bathtub where she would actually practice her mask removal years ago for her open water cert.. I was talking about when we go to the Carribean. She actually wears a 3mil hooded vest under her 3mil hyperstretch fullsuit with a 3mil shorty over that. I know, but like Mike said some people just get cold. At home she wears a drysuit and is quite comfortable. I just think the problem arises with the hyperstretch that after a couple of dives it becomes baggy and there is a lot of water movement inside which is making her cold. We just got back from Roatan and Utila and after 39 dives there the suit was getting very loose. Hdtran I would like to hear more about your Aquaflite as I have been giving them a look and thinking about one of there custom suits for her with the oceanliner lining.
