User Review: The North Face Dark Star -40

I'm suprised by the reviews. I wonder/would like to know if the reviewers used sleeping pads and wore proper sleeping attire...

I do live in Alaska and have taken this thing all over the state. It has lived up to its price but not its temp rating. I would say this thing is a -30; I've got experience based proof. Last year I slept in the bag just outside of Denali Park in -30 January temps. I did strip down to my base layers but did NOT use a sleeping pad. It was just the bag and the tent floor separating me from the snow below. I was plenty warm in the morning.

The bag is a little narrow but otherwise performs well. I question the temp rating by 10 degrees but am satisfied with my purchase.
