Big Agnes Tumble Mountain
Take only pictures, leave only footprints and sleep in an eco-friendly bag. The Big Agnes Tumble Mountain is a 20-degree mummy bag with 725-fill goose down insulation and a shell made of recycled polyester ripstop and taffeta. Like all other Big Agnes bags, the Tumble Mountain is half of a sleeping system that replaces insulation on the bottom of the bag with a sleeve for a foam pad. The system saves weight and prevents rolling off the pad at night.
