New for Fall 2025: Our Flicker UL gets all-new Pertex® Quantum Pro® shell fabric + Pertex® Diamond Fuse lining fabric in the footbox, plus new and familiar colors
We created the Flicker to achieve maximum comfort and versatility without compromising on weight. Unzipped, it functions as a large quilt on warmer nights and is wide enough to cover two adults in a pinch. The footbox can be cinched tight and partially zipped for greater efficiency on cooler nights. At the bottom end of the temperature rating, the Flicker functions as a full center-zip mummy sleeping bag. With 950+ fill power down and ultralight Pertex® Quantum Pro® fabric, the Flicker series is ideally suited for those chilly summer nights in the alpine or on a thru-hike.
Available in 20 Degree, 30 Degree, and 40 Degree options.

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.

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.

Inspired by feedback from the thru hiking community, we’ve added Pertex® Diamond Fuse fabric to the foot boxes of our UL sleeping bags. The interlocking diamond-shaped yarn resists pilling, providing improved abrasion protection against rough hiker feet.
