Category: Three Season Bags

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

Madison Q. ★★★★★

I toss and turn a lot in my sleep, so the roomy cut of this bag is a game-changer — way more comfortable than the tight mummies I've tried before. The weight-to-warmth ratio is spot on for shoulder-season backpacking trips.

Mia P. ★★★★★

I’m 6’1” and was worried about shoulder room in a mummy bag, but this one lets me move around without feeling trapped. The weight is spot on for shoulder-season backpacking without adding bulk. It hits that sweet spot between warm and breathable.

Christopher C. ★★★★★

Finally able to stretch out without feeling trapped in a mummy bag—the extra space makes side sleeping actually comfortable. Weighs so little I barely notice it in my pack, yet kept me toasty on a chilly 40-degree night.
