I've been looking for something that will wick away the moisture and drys fast... everything I've tried so far becomes damp, then 4:00am, I wake up chilled to the bone. I actually seem to do better not wearing anything. Just got a new down quilt, they recommend wearing something, mostly to protect and extend the life of the quilt. I've reviewed some silk long underwear, the reviews make me a little nervous about spending that much money on something that may not holdup. Anyone here have any experience with silk? Good or bad.
