Deer Park 30°

Down fill Big Agnes System bags geared for the big guys or those who want more space

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?

Smack in the middle of Routt County, just east of Whetstone Reservoir, is Deer Park. Named in the 1870's by the Nichols brothers for obvious reasons, the park was also home to a number of bootlegging operations. The remnants of whiskey stills can still be uncovered if you look hard enough.
