The Lost Ranger UL 3N1 20° sleeping bag is part of our latest evolution of the Big Agnes Sleep System.

It's the only bag you need for 3-season camping, backpacking and everywhere in between. These ultra-lightweight, down-fill bags deliver comfort and versatility no matter your sleep style or temperature preference.
