Old Rag Mountain Ultralight 0° Multifunction Winter Backpacking Quilt

At 22.2 oz for the Regular, the Old Rag Mountain is JRB's 0°F winter backpacking quilt — built for back sleepers and trim builds who want 0°F performance without carrying extra fabric. 1000FP down, Argon 67 shell. Also runs as a hammock underquilt.

Built for Back Sleepers and Trim Builds Who Need 0°F Without the Weight of a Sleeping Bag

Wide winter quilts are cut for side sleepers, larger frames, and restless movers who need that extra coverage when the temperature drops hard. The Old Rag Mountain is cut for people who sleep on their back, don't thrash around much, and don't want to carry excess fabric into a winter pack. At 48 inches across, it covers you fully without pooling underneath you or bunching up when you roll to a side. If you're an average to lean build and a relatively still sleeper — think 5'10", 165 lbs, a back sleeper who heads out in January and occasionally drifts onto a side — this is the quilt. The extra width of a wide winter quilt will get in the way. The Old Rag Mountain won't.

How It Gets to 22.2 oz: 1000 Fill Power Down, Argon 67 Shell

The Old Rag Mountain is filled with 1000 Fill Power down — the highest-grade down available. At 1000FP, significantly less down by weight is needed to reach a 0°F rating compared to 850FP alternatives, which is what keeps a winter quilt under 1.5 lbs. The shell is Argon 67 — a 0.67 oz ripstop nylon certified downproof with a DWR finish — the lightest shell fabric in the JRB lineup. Those two choices together are the reason the Old Rag Mountain hits 22.2 oz at a 0°F rating.

Every Old Rag Mountain ships with a 25% overstuff by weight. Down naturally migrates toward the ends of each baffle over time, leaving the center of each baffle thinner. The extra fill means every section retains enough loft to hold the 0°F rating even after downshifting occurs — no cold spots through the middle of the quilt. The same buffer compensates for loft loss as the down accumulates oils between cleanings.

The foot box is formed using a drawcord, cord-locks, and double-sided Kam Snaps. Snap it closed on the coldest nights for a sealed foot pocket; leave it open on warmer nights and use it as a blanket. Double-sided snaps let you connect a second quilt in extreme conditions.

At 22.2 oz, the Old Rag Mountain carries a full 0°F temperature rating into the backcountry — light enough to justify in a winter pack, and warm enough when temperatures drop hard overnight. This quilt was built for backpackers who refuse to call off a trip because of cold weather.

Also Works as a Hammock Underquilt

The Old Rag Mountain attaches to your hammock using the JRB Underquilt Suspension System (sold separately) and insulates against the cold air beneath — the primary cause of cold-weather hammock discomfort. It fits all gathered-end and bridge hammocks including ENO, Hennessy, Warbonnet, Dutchware Chameleon, and most DIY designs.

Named for the Trail

Old Rag Mountain is where Jacks R Better started. In the early days, the two Jacks planned a weekend loop through central Shenandoah National Park. They loaded up with what gear they had — 3–5 pound sleeping bags, a 5-pound tent, self-inflating pads — and set off with 35–40 pound external frame packs. Old Rag was on the route. One of them had hiked it in his younger days. The upper section is a rock scramble, a fun trip. Key word: younger.

They made it over Old Rag just fine. What nearly finished them was the climb back up White Oak Canyon to the ridge — two fifty-something guys, 40-pound packs, a mountain they hadn't been on in years. At the top, they called it. Motel. Hot showers. A big steak dinner. They drove home the next day and, as Jack tells it, "have never heard the end of it from our wives."

Over the next couple of years they replaced every heavy piece of kit with something lighter — sleeping bags, tents, pads, packs — and eventually started making their own quilts. Jacks R Better was born out of two guys who got whipped by a mountain and refused to let it happen again. The Old Rag Mountain quilt carries that name because this is where the story started.

Handmade in Pennsylvania by Jacks R Better — making quilts since 2004. In-stock quilts ship the same or next business day.
