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

The Big Agnes System

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.

What’s in a Name?

Farwell Mountain has seen its share of boom and bust. This broad mountain has taken lives in mining accidents, card game brawls, and modern day avalanches. The mining boom in the late 1800's brought Chicago entrepreneur, John Farwell, to the area. He had elaborate hydraulic mining practices, which included a 27-mile long water ditch built by Robert Macintosh at a cost of $160,000 per mile. The mine cost him more money than it ever produced.
