The Big Agnes Lost Ranger 15 Sleeping Bag is part of the Classic Down Series, and features the "Big Agnes System." The Lost Ranger 15 is uninsulated on the bottom of the bag and features a pad sleeve to maximize the benefit of the pad insulation, while also providing a great foundational structure for the bag that keeps you centered on your pad all night. When Down or Synthetic insulation is compressed, it loses a majority of it's insulating ability. The Classic Down Series (Fish Hawk 30, Lost Ranger 15, Storm King 0) offer warmth, compressibility and the Big Agnes System bag design. They feature DownTek™ water repellent down fill, a wider (semi-rectangle) shape and InsotectFlow™ construction. If you roll around in your sleep, or feel compressed in traditional mummy bad designs, the Classic Down Series is for you!
