Down fill Big Agnes System bags designed to excel in all conditions and provide more room than a mummy bag

Classic down series bags offer warmth, compressibility and the Big Agnes System bag design. Lightweight enough for backpacking, these bags are designed to feel more like the comforter on your own bed. They provide an overall more comfortable and cozier sleeping experience than ever before with a semi-rectangle shape and Insotect Flow™ construction that keeps the insulation next to your body for more efficient heat distribution. These bags are 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.

What’s in a Name?

Lost Ranger Peak, a few miles south of Big Agnes Mountain, is perched above one of the most beautiful basins in Colorado. In the dead of winter, it could possibly be one of the most inhospitable spots anywhere. Legend holds that rangers from North Park and Hahn Peak arranged a meeting on the peak and one fellow never showed thanks to a late September snow storm. It's a topic of debate as to which ranger lost his way, the answer you get depends on which local ranger station you ask.
