The Lost Dog, logging in at 0°F, features FireLine™ ECO synthetic insulation and a roomy, rectangle-shaped sleeping space with an integrated Flex Pad Sleeve on the bottom. With technical fabrics and construction, 100% recycled, super-warm insulation, and tons of comfort features, the Lost Dog is designed to be lightweight enough for backpacking but cozy enough you'll want it in the campground, too.

The streamlined silhouette and Flow construction increase the thermal efficiency, keeping you warm from head to toe. The Flex Pad Sleeve unites easily with your pad, and as you change positions over the course of the night, will keep you from rolling off your pad. With a nylon ripstop and water repellent shell and a soft, cozy polyester lining, this bag not only provides comfort, but also the durability for seasons of dreamy adventures in the backcountry.
