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

United StatesWarm So Far
I’ve only used it so far when the temperature was 40°and slept in a long sleeve shirt and I was actually too warm and had to unzip the bag. Plenty of room to sleep on my side. Looking forward to testing in colder temperatures. Packs really small and is very light. Will post another review later this Winter

United StatesWarm and comfy, but a few issues
Very comfortable bag and warm, though I’ve only taken it out down to about 40 so far. Definitely a couple of quality issues that have me second guessing my purchase though, given how expensive it was. First of all the drawstring on the hood/collar is very flimsy and doesn’t hold firm after you set it. This was called out on a couple of other reviews as well but I brushed it off because of the overwhelmingly positive response overall. Secondly, one of the seams is a little leaky as I tend to have a few feathers on me in the morning even just after the first use. Not sure where they’re coming from but again, annoying given the price. Third the hood is very shallow and doesn’t comfortable cradle my head even when tightened significantly (and I have a small head). This isn’t a huge deal as I can sink my chin under the collar to compensate but all of these things together really have me questioning why this bag is so popular.

United StatesA wonderful sleeping bag. I feel I really got my money's worth.
The bag is my favorite of the five bags I own. Quality throughout. I like the roominess of this sleeping bag. Not too big and not too tight.

United StatesGreat Sleep
Packs up light and small (fitting into an XS 9L stuff sack). Saves over a pound of weight from my old sleeping bag but is just as warm if not more so. Wide enough that when I'm sleeping on my back I can comfortably let my arms rest by my side. Good improvements in the type of zipper that prevents catching the bag in the zipper. Have enjoyed every use and so thankful for the weight savings.
