I just got a Gerry walk around sleeping bag for hanging out on the porch when it is cold. Looks like one of those as seen on TV lounger robes. I think this will be just the ticket for a box blind or pop up when it is cold. This and down booties over light clothes and I was comfortable in the upper 20's. It goes over your feet or can be rolled up. Size is about like a medium to light weight sleeping bag in it's stuff sack, I will strap it to the bottom of my pack.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
