User Review: The North Face Dark Star -40
Temperature Rating: -40F
Weight: pretty heavy
Price Paid: $215
This is a good sleeping bag. I would say it's kept me asleep comfortably up to -10F, lower than that I would not die but would not have a good dream either, which is normal for -40F bag. It comes with a compression bag, very handy, very worth $200.
The only bad thing is the filling has been coming out of the every line of inseam since the first day I unpacked it, begging me a question, how could North Face let this happens??? I'm sleeping in this bag everyday this winter, and I guess I need to replace it within the next 2 years... I hadn't tried to wash it in the machine, because I'm afraid a decent amount of filling will come out..
