The Big Agnes Sunbeam 15 sleeping bag is filled with cozy, 100% recycled insulation, and has a sleeve that attaches to your pad like a fitted bedsheet to keep you centered on your pad all night long.

  • Features

    • Flex Pad Sleeve stretches to unite with your insulated sleeping pad (sold separately) and, as you change positions throughout the night, keeps you from rolling off your pad
    • FireLine™ ECO synthetic insulation made with 100% post-consumer recycled polyester provides high loft, compressibility, a high weight-to-warmth ratio and durability
    • Streamlined, rectangular shape and comforter-style lining offer plenty of wiggle space without sacrificing the thermal efficiency of a traditional mummy bag
