If the inside of the suit is at ambient why would the underwear CLO value decrease?
There is a pressure differential inside the suit since the gas want to rise. For instance when you are riding a scooter your hand and arm are more squezed. Also a difference beteen breast and back. Small but enough to make a difference. There are some tests on 3Ms thinsulate where they tested it at different pressures and got different CLOs. I don't know however if the fibers themselves are subject to any compression depending on the absolute pressure.
