Big Agnes Anthracite 20

Our Anthracite 20° traditional mummy-style sleeping bag is designed to be taken anywhere and provide rest after a long day outside. Stay cozy with FireLine™ Pro Eco recycled synthetic insulation and stay dry with recycled shell and lining fabrics featuring a PFC-free moisture repellent coating. Lightweight enough to stuff in your pack for summer backpacking but comfortable enough for backyard campouts with the kids, this bag is so versatile and comfortable you’ll want to take it on every outing!
