With 2 ultralight down-filled bags that combine to make a comfortable, versatile sleep system, the modular Big Agnes Lost Ranger UL 3N1 15 sleeping bag easily adapts to the weather and your needs.
Features
- 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
- Ultralight, durable materials with 850-fill-power Downtek™ water-repellent down keep weight to a minimum without sacrificing comfort
- Water-repellent finish is PFC free
- Sleep on either side using the inner bag alone or within the outer bag; 3/4-length, anti-snag 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 a single no-draft, antisnag left-side zipper with zipper garage
- 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
- 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)
- Storage sack and stuff sack included
