Product Info for Big Agnes Lost Dog 0 Sleeping Bag FireLine Eco - Men's

Weighing only 4 pounds and 2 ounces, the Big Agnes Lost Dog 0 Sleeping Bag is extremely light and packable, keeping your pack as managable as possible while you're out in the backcountry. Unlike other Backpacking Sleeping Bags, the Lost Dog 0 uses FireLine ECO insulation, which is 100% recycled synthetic insulation to keep you warm and dry even in the toughest conditions. Like a traditional mummy bag, it has excellent thermal efficiency and keeps you snug to maximize body heat retention. The Big Agnes Lost Dog 0 differs from other mummy bags though by allowing some space for you to move inside the sleep system to get to a comfortable position. If you use a sleeping pad when camping, you can easily attach this sleeping bag like a fitted bed sheet using the Flex Pad Sleeve to the pad, keeping you comfortable all night long.image
