Women's 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?

George Franz opened the Lulu mine in 1914 and named it after his mother. The mine operated it until the mid 1920’s hoping to tap a richer part of the vein worked by the Greenville Mine. Modern as always, Lulu boasted a steam boiler and drum hoist as well as a bunkhouse for workers.
