The Big Agnes Anvil Horn 0 sleeping bag has a Flex Pad Sleeve that attaches to your pad just like a fitted bedsheet, creating an integrated sleep system to keep you centered on your pad all night.


  • Big Agnes System bags with DownTek™ insulation offer a roomy, rectangle-shaped sleeping space with an integrated Flex Pad Sleeve on the bottom
  • Flex Pad Sleeve stretches to unite with your insulated sleeping pad (not included) and, as you change positions throughout the night, keeps you from rolling off your pad
  • 650-fill-power DownTek water-repellent down maintains insulating value even when damp; down has PFOA- and PFOS-free water repellency
  • Streamlined silhouette and Insotect Flow™ construction increase the thermal efficiency, keeping you warm from head to roomy footbox
  • With technical fabrics, compressible insulation and tons of comfort features, this bag is lightweight enough for backpacking but cozy enough for the campground
  • Regular bags fit most pads 20-25 in. wide and 72 in. long; rectangular pad shape recommended
  • Long bags fit most pads 20-25 in. wide and 78 in. long; rectangular pad shape recommended
  • Free Range hood gives you the freedom to lift your head easily; jacket-style hood opening contours to the shape of your face for a comfortable, snug fit
  • Pillow Barn keeps your pillow tucked in tight all night
  • Internal hood drawcord gives you a secure, cozy fit when cinched; low-profile cordlock lets you un-cinch the hood with one hand
  • Free Range footbox creates wiggle room for your feet
  • Antisnag, locking zipper with zipper garage offers a smooth, quick zip
  • No-draft collar; no-draft wedge; no-draft zipper
