The Feathered Friends Flicker UL is one of the most versatile sleeping bags we’ve used. Its full-length zipper and cinchable footbox retains heat on cold nights, but it can be unzipped and used as a quilt. We really like the Pertex Endurance fabric shell, which makes the Flicker UL far more wind- and rain-resistant than other UL bags and quilts. That makes it a good option for camping in ultralight tarps and shelters, especially without a bivy sack.

After testing way too many sleeping bags, I decided that the Feathered Friends Flicker UL 20 Quilt Sleeping Bag is the most versatile and comfortable bag I’ve used in a long time. This bag is stuffed full of 14.7 oz of 950+ down and weighs a total of 25.2 oz in a size regular. I’ve never before used a sleeping bag that remains comfortable throughout such a huge range of temperatures. When zipped and cinched, this bag is cozy down to 15 degrees Fahrenheit on a warm pad. When opened into blanket mode, it’s comfortable up to about 60 degrees Fahrenheit. That’s a gigantic comfort range. Throughout most of that range – 30 to 50 degrees Fahrenheit – I use it like a quilt. The zipper remains underneath me, zipped up only to mid-thigh. I secure the snaps at the draft collar and then let the upper body area of the quilt sprawl. Then I sleep like a baby. – Ben Kilbourne
