Swallow UL 20/30 Sleeping Bag
New for Winter 2025/2026: The Swallow UL gets all-new Pertex® Quantum Pro® shell fabric + Pertex® Diamond Fuse lining fabric in the footbox, plus new and familiar colors
Hands down the most popular bag we've ever made, and for good reason. Compared to other mummy bags in the market, the Swallow is the ideal combination of light-weight warmth with room to sleep thanks to a more relaxed cut (more spacious than the Hummingbird, narrower than the Swift). The Swallow is the definition of an ideal all-around backcountry sleeper that can satisfy a wide range of three-season conditions.
Available in 20 Degree and 30 Degree options.
UL: Ultralight. Pertex® Quantum Pro® water-resistant/breathable fabric with 950+ Fill Power Down
"The Feathered Friends Swallow UL20 is a champ in the world of ultralight sleeping bags. It offers an impressive combination of exceptional warmth, minimal weight, and high-quality materials that few bags in its class can match."
