Superlight down fill traditional mummy bags with the REM Pad Sleeve that transforms your bag into a Big Agnes System 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.

Responsible Down Standard

We're committed to using sustainable products wherever and whenever possible, including the down we use for our sleeping bags and outerwear. We strongly believe in using only down that comes from ducks & geese that were treated ethically, so we, as a company,  have committed to the “Responsible Down Standard”. All of the down Big Agnes purchases for our products comes from an RDS Certified supplier.

What’s in a Name?

The Beryl Mountain Mine was one of a number of mines located near Hahns Peak, north of Steamboat Springs. Beryl's primary commodity was zinc, although tertiary ore included copper, gold, lead and silver. Located and operated on National Forest, the Beryl Mountain Occurrence later became part of the Tom Thumb Mine.
