Featuring a 3-in-1 modular design made up of 2 down-filled bags, the Big Agnes Lost Ranger 3N1 15 sleeping bag delivers adaptable comfort for 3-season camping, backpacking and everything in between.

• System consists of 2 down-filled bags that can be used together or separately, depending on your sleep style and temperature preference
• Maximum warmth is achieved when the inner and outer bags are layered, using offset quilting to minimize cold spots—this combined configuration has a tested lower limit of 15°F
• Using the inner bag alone provides warmth down to about 35°F; the outer bag alone provides warmth down to about 50°F
• 650-fill-power DownTek™ down repels water while maintaining its insulating value
• Water-repellent finish is PFC free
• Sleep on either side using the inner bag alone or within the outer bag; 3/4-length, antisnag ambidextrous zipper stays out of the way when side sleeping
• Inner bag design mimics the award-winning Sidewinder sleeping bag, designed for side sleepers and made to move with you from side to side
• Keep your head snug and warm using the inner bag with jacket-style hood
• Spacious, rectangular-shaped outer bag is constructed with a no-draft collar, no-draft wedge and 2 no-draft, antisnag dual side zippers with zipper garages
• 2-way zippers at both the top and bottom of the inner and outer bags allow easy temperature control throughout the night
• Hand-tuck pockets at the top of the outer bag provide additional hand warmth
• Easy access to the discreet pillow barn on the pad sleeve keeps your pillow tucked in all night
• Outer bag lining and inner bag are made with postconsumer recycled polyester taffeta featuring a PFAS-free water-repellent finish
• Pad Cinch System adjusts to a variety of pad sizes; a self-equalizing drawstring easily connects the bag to the pad, and the middle securement feature provides extra stability
• For the regular-length bag, use a rectangular sleeping pad measuring 20–30 in. wide and 72 in. long (pad not included)
• For the long-length bag, use a rectangular sleeping pad measuring 20–30 in. wide and 78 in. long (pad not included)
• Create a doublewide system bag by mating two 3N1 bags with compatible zippers
• Storage sack and stuff sack included
