Big Agnes Battle Mountain -15°

The hybrid Battle Mountain -15° sleeping bag uses 600 fill goose down on top and more eco-friendly bamboo charcoal synthetic insulation on the bottom. The renewable insulation is derived from bamboo that is burned at 1,500° Fahrenheit to create charcoal, which is then spun into a synthetic fiber. Bamboo has a fast growth rate, consumes high levels of carbon dioxide, and generates up to 35 percent more oxygen then an equivalent stand of trees.


Temp Rating -15°F
Weight 4 lbs 13 ounces (regular), 5 lbs 7 ounces (long)
