The Feathered Friends Flicker YF Quilt Sleeping Bag 20 uses a different material mix than the UL line: 417 g of 900+ fill-power goose down inside a more durable, water-resistant Pertex YFuse 20D nylon shell, with a recycled 20D nylon taffeta (NetPlus) liner. The -7°C lower limit puts it in the same colder three-season bracket as the lighter UL 20, but built from tougher, heavier-duty fabric.
At 793 g total weight, it's noticeably heavier than the equivalent UL 20, a direct trade-off of the thicker 20D shell and lower fill power (900 vs. 950 FP) needed to hit the same temperature rating. Packed volume comes to 8 liters. This particular version has an open construction with no zip to cinch it into a more enclosed shape — it functions purely as a blanket-style quilt.
The down carries RDS certification, the fabric is bluesign-approved and includes recycled content, and the quilt is handcrafted in Seattle. A storage sack is included; a compression stuff sack is not, and this version skips pad loops.
