Our take on the Marmot Idlewild 30 Sleeping Bag

The Marmot Idlewild 30 is a rectangular synthetic sleeping bag rated for three-season use, with a 30°F comfort target. It uses polyester shell and lining with about 56 oz of synthetic fill, weighs roughly 4.2 lb and fits sleepers up to about 72 inches. The rectangular cut and 71-inch width give more room to move than mummy bags, which suits car campers and casual campers more than backpackers counting ounces. Against mummy bags of similar rating it trades weight and pack size for space and a roomier night.
