Why We Like The Lost Ranger 3N1 Sleeping Bag

Whether we're backpacking or car camping, sleeping under summer stars or on top of crunchy autumn leaves, the Lost Ranger 3N1 Sleeping Bag is a cozy camp companion. Similar to a three-in-one jacket, this sleep system features two sleeping bags that can be used separately or mated together depending on the temperature, season, and conditions. Even together, this bag is light and packable enough for backcountry adventures.


  • Lightweight sleeping system with three sleeping bags in one
  • Mated together, 15-degree rating insulates well in shoulder seasons
  • Bags used separately deliver cool comfort on summer nights
  • DownTek hydrophobic insulation retains loft in all conditions
  • Cinch-system pad retainer secures a variety of sleeping pads
  • Outer bag features corner pockets for cuddly wrap-around comfort
  • Mummy bag's hood traps warm air around the hood on colder evenings
  • Sidewinder inner bag design is comfortable for both side and back sleepers
  • Item #BAGZ2C3
