Feathered Friends Flicker YF Quilt Sleeping Bag 40

The lightest model in the YF line, the Flicker YF Quilt Sleeping Bag 40 is also the only one of the three weight variants covered here with a full-length center zip — meaning it can actually close into a more enclosed shape, unlike its colder siblings (the 20 and 30), which remain open blankets. It's filled with 238 g of 900+ fill-power goose down inside a water-resistant Pertex YFuse 20D shell, with a recycled 20D nylon (NetPlus) liner. A +4°C lower limit puts it squarely in summer territory — suited to warm thru-hike nights or as a top layer combined with other insulation in cooler weather. The regular dimensions (157 cm shoulder, 122 cm hip, 99 cm foot girth, rated to 183 cm user height) reflect the standard cut rather than the roomier Wide sizing. At 603 g total weight and a 5-liter packed volume, it's one of the lighter picks in the YF portfolio. The down carries RDS certification, the fabric is bluesign-approved and includes recycled content, and it's handcrafted in Seattle.
