"Exellent bag" - Review of The North Face Inferno Endurance Sleeping Bag: -40 Degree Down

I work outdoors on the west slope of the Colorado Rockies . I purchased this bag to solve the 20 below zero weather that comes along now and again. The bag works well, sometimes ice accumulates around the face area, the addition of fur around the snorkle area solved that. Padding under you is needed if you are sleeping on the ice or snow. As to the bag being too much for a mild night, just unzip it and let a little air enter . Well worth the investment, if you are serious about being in the cold .
