So here's my situation. I'm going on a guided Alaskan moose hunt in unit 20, 2nd and 3rd week of September. I don't do backpack hunting normally but for this hunt I need to supply my own sleep system. I want to keep tent, pad and bag under $600. I need to keep weight down somewhat as we're hiking to spike camp. What would be a good combination for around $600 and hopefully under 10lbs? Also I'm guessing a 0 degree bag would be best?
