Our take on the Big Agnes Fly Creek UL Zip Quilt Sleeping Bag

The Fly Creek UL Zip Quilt is a down backpacking quilt from Big Agnes that opens flat like a blanket and zips into a hoodless bag shape. It uses 850-fill-power down in a nylon shell, so it packs small and light for its warmth. The open-zip design suits side sleepers and warm-weather hikers who dislike a closed mummy bag. Against closed mummy bags of similar fill, it trades a hood and full draft protection for versatility and lower packed weight.

Best forUltralight backpackersSide and stomach sleepersWarm-weather and summer tripsHikers who want a bag-and-quilt hybrid
Pros
  • 850-fill down gives strong warmth for the weight
  • Zips open into a flat quilt for warm nights
  • Packs down small in a backpack
  • Hoodless design saves weight and bulk
  • Works as a bag or a blanket depending on conditions
Cons
  • No hood, so the head needs a separate hat or balaclava
  • Draftier than a closed mummy bag in cold or windy weather
  • Quilt-style edges can let cold air in for restless sleepers
  • Not the pick for freezing or shoulder-season nights
