One comforter that works in February and in July. Wool is also hypoallergenic. Both of those come from the way wool handles moisture, rather than from how much heat it traps.
Warm damp air is what makes bedding feel hot and close. Wool pulls that damp out of the air and holds it inside the fiber, up to 30 percent of its own weight, then lets it go again. The heat leaves with it. Dry air is what is left against your skin, and dry air is what feels cool. When the room cools down instead, wool traps warm air in its crimp and holds it against you, so the same comforter reads as warm.
Wool also keeps dust mites out, and it does that by keeping the air dry. Mites drink from the air rather than from water, so they only live where it is damp. The air under this comforter never gets there.
The wool arrives as a cohesive layered pad rather than loose clusters, so it can be anchored by hand at points across the whole comforter and stays put for years. Corner loops at each end tie into the ties inside a duvet cover, which stops the wool sliding to one end overnight. The cover takes the laundry. We make covers too, as an organic cotton sateen duvet cover, cut to match these sizes.
Wool runs lighter than you would expect for the warmth: about 6.5 pounds at Twin, 9 at Queen and 11.5 at King. That is a pound to three pounds under the cotton comforter at the same size.
The wool comes from certified organic farms in New Zealand, where cutting skin from a lamb's hindquarters has been illegal since 2018. Oregon Tilth certifies this comforter to the Global Organic Textile Standard, the wool inside it as well as the sateen over it, under license GOTS-10229, and an auditor walks the supply chain every year.
Care is a damp cloth and the sun. Spray a mark with three parts water to one part vinegar, or a little mild laundry detergent, then set the comforter in the sun until it dries. It never goes to a dry cleaner, so no solvent ever touches it. Solvent strips wool's natural lanolin and flattens the crimp that keeps it full. Water and agitation will felt wool, and felted wool does not come back, so it never goes in a washing machine either.
Wool comforter and wool duvet are two names for the same bedding, and this is the insert that goes inside your cover. Sheep make wool, so this one is not vegan. It lasts 10 to 15 years under a cover, hand-tufted in New Jersey beneath a sateen woven in the United States.
