So far my sleep system is the Achilles heel of my get home bag. The longer you compress down or synthetic fill the less effective it is at re-lofting and keeping you warm when you need it. Wool and fleece don't compress/ pack well. It's not practical to have an uncompressed sleeping bag in my vehicle and a wool or polyester blanket that's warm enough to see me through a winter night would be huge and unpackable. I know some of you guys are going to say that you're not going to sleep, just fast pack it all the way home. Well, what if you're 60 miles from the house? What's the solution here fellas? The only thing I can come up with is a Siberian log fire, but that's not too stealthy.
