Women's down fill Big Agnes System bags to excel in all conditions and provide more room than a mummy bag

The women's Ethel 0 sleeping bag is a lightweight companion for adventurous women who camp, backpack, and venture everywhere in between. Women’s Classic bags are designed to feel more like the comforter on your own bed. They provide an overall more comfortable and cozier sleeping experience than ever before with a semi-rectangle shape and Insotect Flow™ construction that keeps the insulation next to your body for more efficient heat distribution. The new polyester mini rip-stop microfiber shell fabric is softer than ever with a water repellent finish. These bags are taller across the top so you can roll over more freely while the Free Range hood allows you to move unrestricted while staying hooded. They’re so comfortable, you won’t want to go home.

What’s in a Name?

Mount Ethel features a large summit at 11,924 ft., reached via the Lake of the Crags trail, with great views of surrounding peaks - including Mount Zirkel. She casts her shadow over Roxy Ann Lake every evening. Steamboat Pilot newspaper clippings describe the view from Ethel's apex: "From this vantage point, the Continental Divide really does resemble the backbone of the nation."
