I'm going to be getting into winter backpacking.
However, the one thing that seems to really keep me up, even in summer, is breathing extremely cold air.
It just bothers me and keeps waking me up.
I was thinking that one way around this could be to suspend a small 2×4 foot down blanket over my head while I sleep.
it would be about 6' above my head and help trap warm air near my body.
Many sleeping bags do something similar by having a hood that you can use to wrap your entire head.
Has anyone experimented with this?
