Wool Sleeping Bags for Backpacking & Cold Weather

Natural fiber sleeping bags made in the USA from US wool. The Rewilder is a 4 lb, 20°F (10°F option) backpacking bag that keeps insulating when damp, breathes instead of trapping sweat, and contains no synthetic fibers, foam or DWR — the lightest all-natural sleep system we know of. The Aurora Borealis is a wider, loftier cold-weather wool sleeping bag for camp, cabin and car camping, with 2″, 3″ and 5″ loft options and a queen-size quilt mode. Both take a merino wool sleeping bag liner (or WeatherWool®) next to skin; add the washable merino sleep sack or the wool felt bedroll blanket for extra warmth. Searching for an organic sleeping bag or a non toxic sleeping bag? Every bag here is exactly that: organic cotton shell, Eco Wool™ batting and a beeswax finish — no flame retardants, no PFAS, no synthetic fibers. Repairable, re-waxable and covered by our lifetime workmanship guarantee; ships in 2–5 days from Burnsville, North Carolina.

Find your wool sleeping bag

Start with the trip, not the material: how cold will it get, and are you carrying the bag or driving it in? The Rewilder is the backpacking bag; the Aurora Borealis is the cold-weather camp bag. Every one is US wool, organic cotton and beeswax — no synthetic fill, no PFAS.

Carrying it? Rewilder.

The lightest all-natural backpacking bag we know of. Yes, about three times a down quilt — what the ounces buy is insulation that keeps working damp, no clammy shell, no cold spots and decades of use. Choose 20°F for three seasons, 10°F if your nights drop below freezing.

Driving it in? Aurora Borealis.

A roomy rectangular winter sleeping bag that opens into a queen-size quilt and joins to a second Aurora for two. Pick the loft for your coldest night — 2″, 3″ or 5″ — and don't count the ounces.

Build the sleep system.

Warmth is the bag plus what's under and inside it. Add the merino liner (about +10°F, 30 oz) and a wool sleeping pad under either bag. Not sure? Find your sleep system →
