Fly Creek UL 50F Down Zip Quilt

Jump to: Our Verdict / Features / Specifications

Versatile, lightweight, and responsibly made, this dual-purpose quilt adds smart functionality to warmer-weather kits.

Big Agnes says: 

A large, luxurious quilt by evening and a snug sleeping bag at night, all at about one pound. Hang out by the fire in quilt mode – then when it gets late, simply retire to your tent, turn the Flipit™ Footbox inside out, and zip up for a cozy night’s sleep. Featuring Big Agnes Signature Diamond Quilting with premium down insulation, and ultralight NetPlus® fabric made from recycled fishing nets, this hybrid bag has you covered on warm weather backcountry missions.

Our Verdict

The Big Agnes Fly Creek UL 50F Down Zip Quilt blends the openness of a quilt with the structure of a mummy bag, offering flexibility for spring and summer nights. At 424g with a 227g fill weight, it’s clearly aimed at those counting grams, in warmer summer months. 

The FlipIt footbox design transforms into a fully enclosed foot section for cooler nights, or can be flipped open to convert the quilt into a traditional blanket-style layout.. Diamond baffles help the 650 fill down loft evenly, avoiding the usual cold patches along seams. 

The fabric is a recycled 10D nylon ripstop made from discarded fishing nets, which holds up well for such a light material. Packed down, it takes up little space at 17 × 20cm, making it ideal for minimalists. It can also be incorporated into a pre-existing sleep system to add warmth.
