New for Fall 2025: 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

Details

  • Mummy shape (medium width) with #5 YKK two-way, separating zipper with locking sliders
  • Passive collar provides an extra cushion of down around your neck to trap the heat
  • Trapezoidal footbox allows your feet to fall in a natural pose without compressing the sides
  • Pertex® Diamond Fuse 15 denier footbox lining that offers more abrasion protection for more nights at camp
  • Continuous baffles let you position the insulation where you need it

UL FAQs

Our UL-series sleeping bags get upgraded with a quieter Pertex® Quantum Pro® shell fabric, as well as the introduction of Pertex® Diamond Fuse lining fabric in the footbox for more long-term abrasion resistance.

Undyed fabric is just that: undyed. Both the shell and lining fabrics (except for the footbox lining) have not been treated with dyes (color), so it is an option for those looking for the same benefits of Pertex® Quantum Pro® but with environmental advantages such as reduced water consumption and a lower chemical footprint.

Undyed UL sleeping bags will take longer than our other colors to manufacture. Please allow up to 2 to 3 weeks for production.

Pertex® Quantum Pro®

We pair this ultralight Pertex® Quantum Pro® fabric with 950+ fill power down for one of the lightest sleeping bag combinations out there. Water-resistant, breathable, and surprisingly durable, this fabric will help you go the distance.
