Yes, I am very low-tech with matches! I always burn my finger when I use a lighter. I also carry a packet of REI emergency matches - the ones that burn like candles!

I happen to have a 10-degree bag. The bloody thing cost over $450! It weighs 2#14 oz - same weight as a lot of 30 degree bags. My only other bag is a 45-degree bag. If I were climbing, using clothes to supplement a lighter bag would be great. However, when I solo backpack I am either walking or camping, in which case pound for pound, the heavier sleeping bag is the most efficient. I am also a weather whimp! I simply stay put when the weather turns sour.
