Fish Hawk 30°

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

DownTek™ Water Repellent Down Insulation

Down sleeping bag insulation has long been the favorite of backpackers, thru-hikers, and mountaineers due to its relative light weight and ability to pack down small. While down bags generally cost more and require more care to keep dry in humid conditions, the soft feel of down is unsurpassed and extremely popular.

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?

Fish Hawk Lake and trail lie to the south, southeast of Mt. Ethel in the Mount Zirkel Wilderness area. At one time this was the summer home of the osprey or fish hawk, raptors who can spot prey 130 feet above the surface of the water.
