Crawl into cozy no matter the weather with the Big Agnes Anthracite 20 Degree sleeping bag. The traditional mummy shape and lofty synthetic insulation offer versatile performance across the seasons without hogging up pack space.


  • Synthetic warmth for reliable performance in any conditions: Big Agnes' own FireLine Pro synthetic insulation consists of multi-denier, short-staple fibers with a high loft to effectively trap heat. These fibers compress tightly for packability and have the added bonus of retaining their insulating properties even if your bag gets wet.
  • Warmth-efficient fit: The streamlined mummy shape helps keep weight to a minimum and makes it easier to stay warm all night long. A two-way zipper lets you vent the bag on warmer nights.
  • Anti-draft features for greater comfort: A cinchable hood has insulated tubing along the upper opening and collar for sealed-in warmth. The zipper also has anti-draft protection so cold air can't sneak in.
  • Conscious construction: Insulation, lining and shell are all constructed using recycled materials without sacrificing durability.
