I live on my bike. Everything got stolen 2.5 mths ago and since I didn't have the money to replace all and winter was over (I'm in southern Cal), decided just to buy a $5 blanket at Wallyworld plus the sleeping pad and tarp I always use. Most nites it keeps me warm enough. The only disadvantage is that I can't hide stuff like I did with the bag (wallet, mace, phone).
