>>662249Yeah, look for something made of feather down if the rain and moisture levels aren't too high, otherwise synthetic-hybrid combos would be better for your trip. Be warned though, the good hybrid bags cost quite a bit more.
Alternatively, you can get a feather down bag with a mil-surp bivy bag which is what I used when I was spending a summer in the Rockies. For a mil-surp bivy bag I pay about $10 dollars but only because I live close enough to a military base and can check stores that sell it. I wouldn't pay more than $20 for one.
