I would agree with Norad, but kick the temp up a couple of degrees.
Bought one this spring and brought it up for the yearly pilgrimage to Northwest Ontario. Ended up missing my North Face Cat's Meow.
Temp's dipped. interior cabin temps probably in the low 30's. Note: I'm a cold sleeper. Could sleep, but not comfortably.
Bag is well made for it's price, but cotton lined. Would be ok for a heavy summer bag in dry conditions, allowing time to hang it before breaking camp.
Overall, not a bad bit of kit for the price.
