Big Agnes Yampa 45° 650 DownTek Sleeping Bag

Warm weather bikepackers, backpackers, and anyone who can appreciate the ultra-compressibility of a lightweight, 650 fill DownTek™ Big Agnes System bag, unite! The Yampa offers cozy quilted construction with a lofty fill that compresses for optimum packing when a super warm bag isn't needed. Paired with a UL tent and pad, or maybe a hammock, and you've got a premium set up with maximum comfort.
