Temperature Rating: -20 F

I have used it extensively in every type of weather. The temp rating is way overrated. The last time when I was in an expedition tent set up around 2000 m in the mountain, I took everything off except my underwear and a long sleeve 50% wool military top and the corresponding bottom, then slept inside this bag.
The temp got down to -0.5 C. My pad, although 12 mm thick, was not so good, so it was right before the sun up, I started feeling the cold from underneath. It was not that bad, but not under-estimable either.
Oddly, my feet never got cold. I kept changing my position until I got up. I do not know, under a better pad and with a little more garment on, how it will perform. I have the long one. I compressed it in an XL size stuff sack. It does compress, but do not expect a miracle. Even inside the stuff sack, it filled so much space in my bag that I could not organize properly; heavy as well.
It is not bad for a $70 bag, however, do not count too much on it under freezing temperatures.
