The Firebelly is a 30º down trail quilt designed for the cold-weather, trail-blazing adventurer. Our newest version is designed to adapt to any environment as a minimalist sleeping bag, top quilt, underquilt, or your go-to insulator for travel. With our new buttery-soft Atmos X™ fabric and responsibly-sourced DownTek fill, the Firebelly brings comfort wherever you roam.
Ready for every adventure, the Firebelly can be used as a minimal sleeping bag, as a hammock top quilt or crucial hammock underquilt to keep you warm down to 30°F. Create a cozy footbox with YKK button snaps and shock cord ends. Ditch the traditional sleeping bag and snap in the Firebelly to your pad using the included sleeping pad straps for a lighter weight top layer in the tent.
For the new version of the Firebelly, we increased size by 20% and gained only an ounce in weight. Measuring 54 inches wide by 88 inches long and weighing 24 oz, the Firebelly provides expansive warmth coverage without the bulk.
Atmos X™ fabric
We’ve upgraded the Firebelly’s fabric to our new Atmos X™ material - a stronger, lighter, and more abrasion-resistant 15D nylon ripstop. Atmos X has an unparalleled ability to retain body heat and is DWR-treated. The Firebelly will become your go-to for packable warmth.
The Firebelly is constructed using Insotect Flow™, a honeycomb structure of insulation gates that ensure even distribution of warmth, eliminate cold spots, and keep you toasty. With Insotect Flow, your insulation will stay in place trip after trip.
The Firebelly uses 750-fill DownTek - a responsibly-sourced down with a PFC-free water repellent treatment. DownTek absorbs 30% less water and dries 60% faster than untreated down, so it will retain more loft and keep you warmer after exposure to moisture.
