    Lost Dog Sleeping Bag

    Say yes to that next backpacking trip with the 45-degree Lost Dog Sleeping Bag from Big Agnes in your pack. While you won't want to trek too high into the alpine, those desert excursions and forest service trails are perfect for this lightweight, fair-weather bag. The synthetic fill keeps the Lost Dog light and easy to pack while also warding off water in late May storms.

    When it's time to call it a night you'll forget you're even in the backcountry—the Free Range footbox and Free Range hood give you room to wiggle while the pad retainer keeps your bed in one piece. With all that comfort, you'll wake up rested and ready for another day on the trail, the lake, or of simple relaxing at the campground.
