I have a DUI 450CLX and two sets of underwear. I use the DUI 200G Thinsulate for cave diving in 72 degree water. For anyting colder you will find me in my 400G Thinsulate with usually a pair of silk long underwear against the skin and a set of Duofold polypro/wool long underwear on top of that. I usually stay quite toasty with this combo. Wear it locally in the quarries during the winter and also a few years ago in the PNW in 45 degree water.
Diving isn't fun for me if I am cold.
