Welcome home to your wool duvet.
The one duvet that stays warm in winter and cool in summer, and that's easier on your allergies than the down or foam it replaces. Everything it does, and how to get years out of it.
The last duvet you buy for either season.
Most duvets only hold heat, so you end up owning a light one and a heavy one and still wake up too warm in spring and too cold in fall. Wool moves your body's moisture instead of only trapping heat, and that is what lets a single duvet feel right in every season.
Warm in winter, cool in summer, from one duvet.
What makes you too hot or too cold under a duvet is moisture more than temperature. Trap sweat against your skin and you overheat. Let your warmth escape too fast and you get cold. Wool handles both, pulling moisture away when you run warm and holding heat in when the room cools.
So the microclimate under the duvet stays even, and one duvet carries you through July and January alike. It absorbs up to 30% of its weight in moisture before the surface ever feels damp. If you have kicked a duvet off at 2am, wool is the fill that stops it.
Most bedding is where dust mites live. Wool isn't.
Your duvet is the biggest piece of bedding you own, and dust mites make their home in bedding. Wool is one of the only fills they cannot live in, and it is the fiber itself that keeps them out, not a spray that wears off. Fewer allergens over you all night means fewer stuffy, sneezy mornings.
Lanolin turns them away
Wool's natural wax is hostile to dust mites and the bacteria they feed on, so they never establish.
Too dry to live in
Wool keeps its microclimate below the humidity mites need, so the duvet stays a place they cannot survive.
Nothing sprayed on
The resistance is built into the fiber, so it never washes out or wears off the way a treated cover does.
Real wool, tied in by hand so it never bunches up.
Inside is long-staple GOTS-certified organic wool, held in an organic cotton sateen shell. Long fibers keep their loft for years instead of matting down, and they carry the same temperature and allergy work over the whole bed that the wool pillow does under your head.
It is hand-tufted, not sewn into channels. Twisted-cord ties are tied by hand every 20 centimeters, so the wool stays exactly where it was placed and never drifts into the corners or leaves a cold spot.
Slip it in a cover, and forget it.
A wool duvet asks almost nothing of you. There is no fill to adjust and nothing to swap out by season. Set it up once, the way you would any duvet insert, and it just works for years.
Use a duvet cover
The duvet is the insert. Slip it into a removable cover, an organic cotton percale or sateen, and button or tie it in at the corners.
Let the tufts hold it
The hand-tied tufts keep the wool in place, so you never have to shake it back into shape or fight cold spots.
Keep it all year
Because wool regulates instead of only insulating, this is the duvet for every season. There is nothing to store in a closet half the year.
You breathe against it all night. There is nothing in it but wool and cotton.
A duvet covers most of you, all night, every night. What it is made of is the air you breathe while you sleep, so we made it clean from the fill all the way to the thread.
Most duvets hide a lot. Down that carries dander, or polyester fill that is fine microplastic, wrapped in shells finished with chemical softeners and stain treatments. The whole of this one, the wool fill, the cotton shell, the thread, and the dye process, is certified organic under the Global Organic Textile Standard, license GOTS-10229, audited by Oregon Tilth and searchable by anyone.
The wool is long-staple, cleaned with biodegradable detergent, left undyed in its natural cream-to-tan color, with the lanolin that keeps it hypoallergenic still on every fiber. Clean the whole way through, so the air under the duvet all night is just fiber.
The list most duvet makers hope you never read.
None of it has ever been in a Circadian duvet.
Wash the cover. Let the wool be.
Wool is close to self-cleaning, the lanolin that keeps mites away keeps odor down too. The duvet inside barely needs you.
The cover washes, the wool doesn't
Keep the duvet inside a removable cover and wash the cover, not the wool. Spot-clean the duvet itself if something reaches it.
Never machine wash the wool fill. Water felts and mats it for good.
Air it in the sun
Drape it in indirect sunlight for a few hours and give it a shake. Sun and fresh air refresh the wool and revive its loft with no washing.
Dry-clean only in the rare case it is heavily soiled.
It holds its loft
The hand-tufts and long-staple wool keep the duvet full and even season after season, so it stays with you for ten to fifteen years.
