Three ways to sleep. One bag to own them all.

The Lost Ranger UL 3N1 15° is a modular, ultralight sleep system designed for backpackers who want flexibility without compromise. It combines two down bags into one system: an inner bag for cooler nights, an outer quilt-style wrap, and the ability to layer both together when temperatures drop. With the Padlok™ Sleep System, it stays attached to your sleeping pad so you can move freely without sliding off. Warmth, comfort, and adaptability meet lightweight performance. 

Constructed with high-quality 850 fill DownTek™ water-repellent down, and recycled ultralight ripstop shell fabrics that resist the elements, this system delivers top-tier thermal efficiency and packability. Thoughtful features like two-way zippers (top and bottom), anti-draft collar and zipper garages, a hood on the inner bag, and a Pillow Barn for head comfort make it more than just warmth — it’s comfort engineered for real adventure.

CARE & MAINTENANCE

Store your bag in its mesh storage sack (or hanging) in a cool, dry place away from heat. When it’s time to wash, use a front-loading washer (no agitator) on a warm, gentle cycle with a down-specific soap like Nikwax Down Wash Direct. Rinse twice, then tumble dry on low with clean tennis balls to restore loft. For extra fluff, finish with short 5-minute bursts on high heat, letting the bag cool between cycles. Never use bleach, fabric softeners, irons, or dry cleaning — they’ll damage your bag.
