I spend alot of nights out in a year, and have several bags, I basically agree with what has been said, but you need to look hard at the conditions you will be using it in, the biggest mistake backpackers make is to hot of a bag, if your summer time campin you don,t need the extra weight the additional money etc, and a lighter bag can always be stuffed inside a old duck canvas bag for winter campin. if your only huntin weather camping then go for a better bag, for my summer bag I use a down bag, good for 30 deg it's carry weight is 2 1/2lbs it fits inside a gore tex bivy real well, for winter camping I use a Cabelas synthetic bag good to - 20 and I also sleep in a full fleece suit with toasty botties when needed, by throwin a couple of disposable hand warmers in a bag the temp can be raised considerably. if your real serious about spending the nights out, do not skimp on your bag and just as important your sleeping pad. your life just my depend on it.. h2m
