Product Info

The Big Agnes Lost Dog 45 Sleeping Bag is the warm-season sleeping bag for adventurers who want something mobile enough for backpacking but refined enough to satisfy the tastes of the discerning car camper. A thermally efficient Flow™ construction with a streamlined silhouette works in conjunction with 100% recycled FireLine™ ECO synthetic insulation for a luxurious fit that is just as functional lounging around base camp as is it is keeping you cozy in your tent when the sun dips low in the sky. Its Flex Pad Sleeve keeps your pad in place, perfect for those tossy-turny types who could use a little help getting a good night's sleep outdoors.
