I'm puzzled. I always hear how at 100 feet a 7mm (or whatever) drysuit is compressed to the thickness of a piece of paper (Zig Zag, I assume) and has only a fraction of its insulating value left. But then I am also told that the precompressed neoprene on a DUI200 will give good insulation even when flooded. Logically, it would seem that the value could be no more than that of a loose filling 1/8" wetsuit DUI also claims (I seem to recall reading) that their thinsulate retains 80% of its insulating value wet, which seems preposterous since most of the insulation value of these kind of materials are in the airspaces between rather than in the fibers. And then, DUI also are the ones who told me I'd use much less air in a drysuit :-) >When diving in cold water a flooded neoprene suit gives a much better thermal >protection than a flooded shell suit when you need it at the long, shallow >deco >stops.
