Sleeping in the Big Agnes Lost Ranger 15°F long bag is like sleeping in a bed, with a mattress under you for cushioning comfort and blankets for insulation.

  • The underside insulation has been eliminated and replaced with a sleeve for the Big Agnes REM Air Core Pad or any 20-in. wide pad, sold separately
  • Superlight, 15°F modified mummy sleeping bag features 650 fill-power goose down insulation—perfect for use in cold, dry weather
  • Continuous, oversized draft wedge insulates the connection between the bag and pad to prevent cold air from entering
  • Nylon ripstop shell with a Durable Water Repellent surface treatment sheds water; soft, breathable nylon taffeta lining cocoons you in comfort
  • Built-in pillow sleeve allows you to stuff a jacket or a backcountry pillow inside and keeps it in place all night long
  • Contoured, down-filled collar at the top of the bag seals around the neck to prevent warm air from escaping and cold air from entering
  • Two-way, full-length, locking zipper with big, easy-to-grab zipper pull
  • Fabric stiffeners on both sides of the zipper prevent the zipper from snagging
  • Large 3-in. diameter draft tube located behind the zipper prevents warm air from escaping and cold air from entering
  • Choose right or left zipper; bag will zip to another bag with opposite zipper configuration in the Classic Series
  • Includes a stuff sack and large storage bag
