Thanks guys I am going to use a big Agnes q core pad as I am side sleeper. I am planning on staying in bag only coupe nights. Last year the area I was got to 6 degrees a few nights. Why I considered a 0 degree. I plan on taking me a thermal set to sleep in. I am looking at mountain hardwear and western mountaineering bags. I have a ultralight 2 man tent made by Kelty. I be camping at or near 11000 feet
