User Review: Big Agnes Encampment 15°

I am female, 5'8", 130 lbs, a veteran backpacker / camper in a variety of conditions. I bought this bag for expedition camping (i.e. staying in one place for a few weeks once you get there...). I rather like the stability of the Thermarest-like insertion and the bag is roomy and comfortable, however, it is not a "15 degree" bag - I was cold even in 30 deg weather.
