The Big Agnes Anvil Horn 30 Degree Down Sleeping Bag is the comfortable end to your day on the trail. Filled with DownTek, this sleeping bag traps in your body heat and won't lose its ability to insulate if it gets wet. A DWR treatment on the ripstop shell works to prevent that by shedding dew and condensation, while a taffeta lining is comfortable against your body. The Flex Pad Sleeve enables the sleeping bag to drop insulation from its bottom half, and ensures you'll stay put on your pad all night. A draft tube prevents chilly gusts from ruining your night, while the Free Range Hood includes your head and neck in the warmth without restricting your movement.
