Feathered Friends Swift YF 20 Sleeping Bag

The Swift YF 20 combines the wide Swift cut with the water-resistant YFuse shell, filled with 529 g of 900 fill-power goose down for a -7°C limit rating (-2°C comfort) and a total weight of 892 g — the heaviest bag in the Swift/Swallow YF family, reflecting both its extra room and its lower fill power compared to the 950 FP UL models. The 20D Pertex YFuse mini-ripstop shell and 20D recycled NetPlus nylon taffeta liner prioritize weather resistance over minimum weight, and the mummy shape uses continuous horizontal baffles with a full-length two-way zipper and draft tube (no draft collar here). The adjustable fitted hood suits users up to 182 cm, and a trapezoidal foot box adds room. Packed volume is 9 L; both stuff sack and storage sack are included. For hikers who want the roomier Swift fit with a shell that handles condensation and light rain better than the ultralight Pertex Quantum Pro bags, the YF 20 trades roughly 70 g against the Swift UL 20 for that shell durability at a similar rating.
