Big Agnes - Lost Ranger 15

The Big Agnes Lost Ranger 15 sleeping bag offers warmth, compressibility and the Big Agnes System bag design. Lightweight enough for backpacking, this classic down bag is designed to feel more like the comforter on your own bed. The Lost Ranger provides an overall more comfortable and cozier sleeping experience than ever before with a semi-rectangular shape and Insotect Flow™ construction that keeps the insulation next to your body for more efficient heat distribution. This bag is taller across the top so you can roll over more freely, while the Free Range hood allows you to move unrestricted while staying hooded. So comfortable you won’t want to go home. Now available in Long Wide!
This bag uses a full pad sleeve design; the bottom of the bag is non-insulated to save space and weight. It requires a 20-inch wide pad underneath (sold separately) for insulation.
