Sorry I know there is already a bunch of sleeping bag threads but I can't really find the answer im looking for so ill try here. Ok so im getting into overnight/multiday hiking and will also be doing overnight/backcountry snow camping next year. Im struggling to work out what temperature bag i need. I generally find i sleep warm, but I want to be able to use this bag all year round so im thinking a -10 down bag is way too hard-core. Im thinking more a 0 rating and in snow ill just layer up more or buy a liner to go with it. I don't mind if I can't sleep in my jocks, ill happily wear thermals and a big jacket if need be. Am I on the right track here?? Will 0 degrees still be too warm for the other 3 seasons? I can't see why if im too warm i can't just unzip it and wear only half of it. Im pretty sold on the idea of down rather than synthetic and im prepared to pay the extra price. I will generally be skiing Hotham region and hiking in the Vic high country. Thanks for your help!!
