Hi All. I know this is probably a common question as to what is the most effecient way to gain some wind protection and a few degrees extra warmth in the fringe seasons (not full-on winter camping but down to possibly upper/mid 20s). I am considering tarp doors, sock, and now considering an under quilt protector. My thinking is that the UQP will protect from wind and also trap a bit of heat. The sock will do the same but also trap heat on top, but possibly create some condensation issues and be a bit heavier/bulkier. I am leaning toward the UQP because it would come up the sides and pretty much keep most of the breeze off of me and be the lightest trade-off (other than built-in doors). In my thinking process, it seems like the closer the air trap, the more efficient it would be, ie UQP again. Having no experience with any of these options would love to get some opinions. Thanks.
