Most of us have a reflective emergency blanket or two in our BOB's, but what else is there. I keep trying to look through military surplus websites (anyone recommend a good one?) and sporting goods stores, but I want some suggestions. Lets stick to stuff for a BOB, not for larger type packs. I also keep 6 hand warmers in my maxpedition fatboy jumbo at all times. Its not much heat, but it does feel good.
