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.
Every Big Agnes bag requires a pad to provide insulation on the bottom.

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. The jet stream is most comfortable when resting on top of this flat-topped peak. Even on huge snow years, the summit of Lost Ranger is scoured to the frozen ground. Legend holds that rangers from North Park and Hahn's Peak arranged a meeting on the peak and one fellow never showed thanks to a late September snowstorm. It’s a topic of debate as to which ranger lost his way, and the answer you get depends on which local ranger station you ask.

Classic Series Updated DownTek Bags

Updated for 2015, the Classic Down series offer warmth, compressibility and the Big Agnes System bag design. Classic Series bags combine a roomier contour shape with a narrower pad sleeve to provide an overall more comfortable and cozier sleeping experience than ever before. We’ve also redesigned the bag to be taller across the top so you can roll over more freely. The ergonomic hood gives you more range of motion so that you can move unrestricted while staying hooded.

Big Agnes System Bags

The Big Agnes System is different than the traditional sleeping bag on top of a sleeping pad. Instead, we unite the two. With our Big Agnes System, the pad slides into an integrated sleeve on the bottom of the bag, and the top two-thirds of the bag is insulated in the traditional style. When insulation material is compressed under your body, it loses most of its ability to insulate. We eliminate the unnecessary bottom insulation and replace it with one of two pad sleeve designs to accommodate the pad which provides the insulation. This design provides a secure foundation and keeps you on the pad all night.
