Read Daveboones reply again. He has some very valid points.
Be mindful of the time of year you will be hunting and the altitude involved. I live in Colorado and have seen snow in August at 10,000+ ft it typicly warms up off & on. I don't know about Idaho Someone else can speak on their conditions.
Dont' skimp on your sleeping bag! Alway's go for the colder rating if it say's 0* ....... Then it is probably comfy between 20 -25*...... I usually encounter between 18* and 30* at nite. So I have a -15* marmot bag.
A sleeping pad is also a MUST....I use a Thermorest....It is thin and lite but without it the cold get's you from the ground up + your shoulder's and back will thank you!You can find some "deals" ....Sierra trading post etc.
You can find good bargains on top quality gear if you look around.
I'll check back and you can pm me as well
More to cover......But gotta run!
