Warm and light
I've only been able to use this bag once so far. It was high up on a windy ridge, 15f temps, no tent just a nylon tarp pulled over for wind and rain protection. I stayed nice and warm all night. I move around a lot when I sleep so I really like the air pad in the sleeping bag idea that Big Agnes uses. I was very comfortable all night. I'm 6'3" 195 lbs. the XL size fit me great.
