We do a lot of snow camping in temperatures down to -30. Unless you are rich enough to afford an Exped 9 this means using a combination of insulated air mat and old school foam pad. I would love to see a special edition Klymit with a super high R value, at least 6.5 but over 7 or 8 would be ideal. How about it Massdrop? I know we are not the only folk who camp in Canadian winters.
