Lost Ranger 3N1 15 (650 RDS DownTek) REGULAR Merc

Big Agnes Lost Ranger 3N1 is a down sleeping bag system that combines two sleeping bags into one versatile solution with three different configurations, ensuring comfortable sleep across a wide range of temperatures. This modular design delivers exactly what its name promises: three sleeping bag configurations in a simple yet highly technical sleep system that attaches to your sleeping pad, preventing you from rolling off during the night. Use the outer bag alone on warm summer nights, the inner bag alone when temperatures begin to drop, or combine both for maximum warmth on cold-weather adventures.

• 3N1 System Bag: Three sleeping bag configurations for comfort across varying temperatures.
• Big Agnes Padlok™ Sleep System Bags attach securely to your sleeping pad, allowing you to move naturally without rolling off (sleeping pad sold separately).
• Pad Cinch System adjusts to a variety of pad sizes. A self-equalizing cord connects the bag to your pad, while the center anchor provides added stability.
• Maximum thermal efficiency is achieved when the inner and outer bags are layered together, with offset quilting designed to reduce cold spots.
• The inner bag is inspired by Big Agnes' award-winning Sidewinder sleeping bag, engineered specifically for side sleepers.
• A jacket-style hood on the inner bag helps keep your head warm and comfortable.
• The spacious rectangular outer bag features a draft collar, draft wedge, and two anti-snag dual side zippers with zipper garages.
• Integrated hand pockets at the top of the outer bag provide additional warmth and comfort.
• Two-way zippers on both bags allow temperature control from either the top or bottom throughout the night.
• The Pillow Barn attached to the pad sleeve keeps a pillow or jacket securely in place while allowing natural head movement.
• Includes a mesh storage sack for long-term storage and a smaller stuff sack for active use.
• For maximum compression, use with a Big Agnes Compression Stuff Sack or Superlight Girdle.
