Up for sale is a vintage Marmot Mountain Works down mummy bag. It's definitely a classic, made in Grand Junction before Marmot relocated to California in 1985. It looks brand-new, and I'm guessing it has seen very little use. It's about 84" long x 31" wide at the shoulders, and it lofts up about 7". There's no temp rating on the bag, but a tag on it says it's stuffed with 28 oz of down. I would guess it's warm down to +15 degrees F. It does not have a zipper, which makes it a little bit of a pain to get into, but also cuts down on the weight. It's only 2 lbs, 14 oz.
