At a time when so many manufacturing processes are high on waste and low on sustainability, we bring you the ALTOS-S. A true backcountry sleeping bag with a positive environmental impact. It’s made with natural fibers and a cleaner, more efficient manufacturing process. The ALTOS-S Ultralight Mummy Sleeping Bag is a large mummy bag that comes in two-different temperatures ratings — the burnt orange +20-degree bag and the TETON orange zero-degree bag. It’s filled with down-like synthetic Spectrum S fill that is warmer than traditional fill without sacrificing comfort. You’ll sleep soundly knowing we made it from natural fibers with the environment in mind. It’s extremely packable and lightweight but still provides a thick, warm loft to capture warm air and provide exceptional comfort.
