Anvil Horn Sleeping Bag

The Anvil Horn 45 Degree Down Sleeping Bag is the lightweight, comfortable bag that helps you recharge between days on the trail. Big Agnes made this bag with DownTek insulation which maintains the compressibility and insulating properties of down, and won't collapse if it happens to get wet. The abrasion-resistant exterior has a DWR treatment to help it shed dew and condensation while a taffeta lining sits smoothly against you. An integrated sleeve eliminates the need for bottom insulation, so the Anvil Horn weighs in at under 2 pounds for your fast and light adventures.


  • Lightweight sleeping bag for summer backpacking
  • DownTek insulation won't compress when wet
  • DWR treatment sheds light moisture like condensation
  • Integrated sleeve keeps you on your pad
  • Draft tube protects you from chilly gusts
  • Free Range Footbox and Hood let you move comfortably
