User Review: MontBell Super Spiral Down Hugger #5
Price Paid: $159
Super lightweight, real down and packs down in a very small stuff sack the size of a Nalgene bottle. Bought both right and left zippers to mate them if needed. They are a close fitting mummy bag so mating them to sleep is not really very comfortable.
We used them at Glacier National Park and at Lake Chelan National Rec area this summer. It was in the 30's and 40's, but I did not get cold. They laundered well, too, and come with an extra cotton bag for long term storage.
