The North Face Aleutian is a twenty-degree mummy sleeping bag with Heatshield Optimal Technology™ SL insulation to keep you warm, even when it gets cold.

Overlapping shingle construction evenly distributes insulation for consistent warmth and uniform loft. It prevents insulation from moving and eliminates cold spots.

Easily compressed and resists breakdown.

Full-length draft tube keeps cold air from coming through the zipper. Easy-grab zipper pull tabs make it easy to get in and out. Silky taffeta lining is soft next to your skin. Durable Enduralite™ outer shell resists wind and water. Hood and chest drawcords are easy to use and seals out the cold. External zippered chest pocket for electronics or food. Stuff sack included.
