The Lost Ranger UL 3N1 0° sleeping bag features a modular ultralight bag design, offering three bag configurations for temperature versatility with a technical, roomy sleeping space that keeps you on your pad throughout the night. How do you stay on your pad? The Big Agnes Pad Cinch System is adjustable to a variety of pad sizes, providing self-equalizing drawstring easily connecting bag to pad.  

The Lost Ranger is perfect for 3-season adventures, serving up pillowy 850 fill DownTek insulation to keep you warm while repelling moisture, all packed into an ultra-lightweight design so you can go farther after a good night's rest. Use the 20° inner bag for hut trips or back-of-the-truck adventures, the 45° lofty shell for warm nights, or combine the two for 0° warmth in variable conditions.
