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.

Looking for the Osprey 30 UL? You're in the right place! The Osprey 30 has been renamed the Swallow 30.

UL: Ultralight. Pertex® Endurance® 10 denier water-resistant/breathable fabric.


"This has become my go-to option for most of my backpacking trips, especially if temperatures are expected to approach or dip below freezing."
