Big Agnes System
The Big Agnes System is different than the traditional sleeping bag on top of a sleeping pad. Instead, we unite the two. With Big Agnes, 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 a sleeve to accommodate the pad which provides the insulation. This design provides a secure foundation and keeps you on the pad all night.
