DownTek™ insulation

The Firebelly 30ºF backpacking quilt features Downtek™ responsibly sourced, water-repellent down. The down is treated with PFC-free bluesign® approved chemistry, for water to bead up and rolls right off. Downtek™ down absorbs 30% less water and dries 60% faster than untreated down, retaining more loft and keeping you warmer after exposure to moisture.

Comfort in moderate temperatures

Our Atmos X™ 15D nylon ripstop is stronger, lighter, and more abrasion-resistant fabric, treated with a water repellent DWR finish. Constructed with Insotect Flow™, the honeycomb structure of insulation, ensures even distribution of warmth, eliminates cold spots, and keeps you toasty. With Insotect Flow, your insulation will stay in place and keep performing trip after trip.


Ready for every adventure, the Firebelly 30ºF can be used as a camp blanket or hammock underquilt. On the ground, ditch a traditional sleeping bag for a lighter alternative by attaching the Firebelly to your pad using the included sleeping pad straps. Create a cozy footbox using theYKK button snaps and shock cord ends.

Frequently Asked Questions

What is a trail quilt?

We define a trail quilt as a quilt that can serve as both a topquilt, minimalist sleeping bag and hammock underquilt on the trail. Our trail quilts also afford you the option of creating footboxes or using it as a minimalist backpacking sleeping bag. Our Bobcat 45ºF, Bobcat 55ºF, and Firebelly are trail quilts because of their packable construction and versatile use cases.

How can I use my Firebelly hammock camping?

The Firebelly can function as either a top or underquilt to insulate you while hammock camping in temperatures at or above 30ºF. For those who easily get cold at night, we recommend using an additional top quilt or sleeping bag when using the Firebelly as an underquilt. As a top quilt, the Firebelly has a nifty footbox feature that keeps your feet warm over your sleeping bag for added warmth.

How do I make a footbox with my Firebelly?

How do I hang my Firebelly as an underquilt?

Check out this video to learn how to use your Firebelly with your hammock.

How do I loft my Firebelly's down?

When the Firebelly 30ºF is compressed for long periods of time, the down fill can appear flat or displaced when taken out of the bag. After you first receive your Firebelly, give the quilt a good shake and lay it on a flat surface for a day or two to allow the down time to loft. Repeat this after storing your Firebelly for any extended period of time.

How do I clean my Firebelly?

The performance of this fill (heat retention!) is directly tied to the "loftiness” of its down. To help your down products retain their loft, please follow our storage and cleaning instructions. Remember, more loft means more warmth. Lofty gear = happy you.

Keep your Firebelly in the best shape by spot cleaning or hand washing when possible. Hand washing your gear with cold water and Grangers Down Wash + Repel is best for extending its useful life, but it can also be cleaned in a front-load washing machine (do not use a washing machine with an agitator).
Washing machine instructions:

  • If the gear is soiled or stained, use the recommended amount of Grangers Down Wash + Repel. Do not use fabric softener, bleach, or stain removal products.
  • Wash the trail quilt by itself using the gentle, cold water setting.
  • Hang to dry, or use the delicate, no heat, tumble setting on your dryer with a clean tennis ball, or dryer ball. Do not stuff back in stuff sack damp or wet.

How do I store my Firebelly?

Where your Firebelly sleeps when you're not using it affects its lifespan. Before storing after a camping trip, avoid gnarly smells and damaged fill by making sure your gear is completely dry. Then, store lightly stuffed in our cotton storage bag (included) or hang in a dry location. This keeps your down gear fluffy when stored for extended periods of time.
