Feathered Friends Swift UL 20 Sleeping Bag

The Swift UL 20 is Feathered Friends' roomiest mummy bag, built with the same wide cut as the rest of the Swift line but pushed to a -7°C limit rating. It carries 529 g of 950 fill-power RDS-certified goose down for a total of 823 g — more fill and more weight than the Swallow bags, in exchange for both extra warmth margin and extra shoulder room. The shell is the 7D/30D Pertex Quantum Pro used across Feathered Friends' UL models, backed by a Flyte 10D recycled nylon liner, with continuous baffles, a full-length two-way zipper, draft collar and draft tube, and a fitted, contoured hood sized for a 183 cm user. A trapezoidal foot box adds volume without extra fabric weight. Both stuff sack and storage sack are included, and the shell is PFC-free. At 823 g for a -7°C rating, this is a three-season bag for restless sleepers who want the wider cut, not a race-weight ultralight. Made in the USA from recycled and RDS-certified materials, it targets thru-hikers prioritizing comfort as much as pack weight.
