Mummy bags can feel claustrophobic, but not the Western Mountaineering Badger GORE INFINIUM Down Sleeping Bag. Wider than the typical mummy bag, the Badger adds extra room in the shoulders, hips, and foot box, so we can shift positions overnight without losing all our heat, thanks to premium 850+ fill power goose down. It's also a versatile sleeping bag that's appropriate for both backpacking and car camping, weighing less than three pounds with a temperate rating of 15F, which works across several seasons and climates.
