I am headed to Idaho in Sept looking for a good light weight sleep system. What do you use and why do you like it. Also you can throw in there what pad you like as well
I did the sleeping bag--bivy thing a few years ago. Never again. The bivy barely was bigger than me and my sleeping bag. One snowy cold night I had it zipped all the way and breathed all of the air out of the bivy waking up with a need for air. There was no room for my boots and jacket in there and they got wet. My suggestion is a light weight tent and sleeping bag and you'll be glad you did.
