Does anyone here have any opinions on the Stansport Emergency/Survival "Sleeping" Bags like these:
Stansport Emergency Survival Sleeping Bag - FOUR BAGS! - eBay (item 160384124772 end time Jan-03-10 00:36:30 PST)
I've used emergency blankets, but not bags, and the bags are much more effective. These would not replace any other pieces of emergency gear, but would supplement the BOB stuff.
