The 100-Night Cool Guarantee

Sleep on it for up to 100 nights. Wash it, travel with it, give it a heatwave. If it isn't cooler than the blanket it replaced, send it back — even used — for a full refund. No restocking fee. No interrogation.

Will I be warm enough in winter?

Yes — nine layers is a real blanket. In winter, layer it under a duvet: warmth of the stack, ventilation through the layer closest to you. Warm without the 2am kick-off.

What exactly is muslin?

Muslin is a loose, open-weave cotton — the fabric baby swaddles are made of, because nothing soft breathes better. One layer is airy and light; we weave nine together for the warmth of a real blanket with air paths running through the whole stack. It also gets softer with every wash.

Size guide

Full — 50×60 in (130×150 cm) — one sleeper or the sofa
Queen — 60×80 in (150×200 cm) — two sleepers
King — 80×90 in (200×230 cm) — full bed drape
King XL — 95×105 in (240×270 cm) — oversize beds

Muslin relaxes slightly with washing; measurements taken at full stretch.

How do I wash it?

Machine wash cold, hang dry. It gets softer with every wash — fully broken in around wash ten. Avoid hot washes and tumble drying to prevent shrinkage.

What if it doesn't work for me?

You have 100 nights. If it isn't cooler than what it replaced, email us and send it back — washed, used, slept-in — for a full refund. No restocking fee.

Warmth you can breathe through.
WHY MUSLIN

Warmth you can breathe through.

Hold it up to the light and you'll see the difference: an open weave that air actually moves through. Nine layers give you the weight and warmth of a real blanket — with escape routes for the heat your body releases all night.

AirLace™ open weave
Air paths run through all nine layers — body heat leaves before it builds up and wakes you.
Warm, never sweaty
Real warmth in winter, a weightless layer in summer. One blanket, three seasons on the bed.
Softer every wash
Muslin is the rare fabric that improves with use. Expect it fully broken in around wash ten.
Oeko-Tex® certified
100% long-staple cotton, tested free of harmful substances. Safe for skin, safe for kids.
HOW IT'S MADE

Woven slow, on purpose.

Most bedding is engineered to feel impressive for ten seconds in a showroom. Muslin is the opposite — a cloth made carefully enough to be at its best in year three, on the bed of someone who washes it often and notices the difference.

It starts as cotton

Long-staple cotton, spun into a fine, soft yarn. No polyester, no blends — a natural fiber the earth knows how to take back.

No. 02

Nine layers, woven as one

The open gauze is woven layer over layer — nine of them — so air can travel through the finished cloth. Hold it to the light and the breathing room is visible.
Washed, never coated
No. 03

Washed, never coated

Every piece is pre-washed so the layers relax into their signature crinkle. No chemical softeners, no finish to wash off — just water doing the work. That's why it keeps getting softer.

HOW TO SLEEP WITH IT

One blanket. Three seasons.

Summer — solo
On its own over a sheet. Enough cover to feel held, enough airflow to stay cool through a heatwave.
Spring & fall — layered
Over your sheet, under a light duvet. The muslin ventilates the layer where heat usually gets trapped.
Winter — stacked
Under your comforter for warmth that breathes. Warm without the 2am sweat — that's the whole point.
One blanket. Three seasons.

FROM THE FIRST 100 NIGHTS

What hot sleepers say.

Placeholder reviews — swapped for verified customer reviews at launch.

“I can hold it up to the window and see through the weave.”

That's how I knew it wasn't another 'breathable' marketing claim. First blanket I've kept on all night in July.

Denise W. Verified Queen · Dune

“We stopped fighting over the duvet.”

I run hot, he runs cold. I sleep under the muslin, he keeps his comforter. Married eleven years, this might be the best purchase we've made.

Sarah K. Verified King · Bone

“Softer at wash five than day one.”

It arrives soft, but keep washing it — it turns into something else entirely. My daughter keeps stealing it.

Claire M. Verified Queen · Mist

“Lighter than I expected — in a good way.”

If you want a heavy weighted feel, this isn't that. If you want to stop waking up sweating, it's exactly that. Wish it shipped in more colors.

IN REAL HOMES

The first squeeze says everything.

Yes — nine layers is a real blanket, not a summer sheet. In winter, most customers layer it under a duvet: you get the warmth of the stack with ventilation through the layer closest to you, which is where sweat usually starts. Warm without the 2am kick-off.

It arrives soft with a gentle crinkle texture, and gets noticeably softer with every wash — fully broken in around wash ten. The texture is what creates the air pockets that make it breathe; it reads rustic in photos and feels gentle on skin.

Machine wash cold, tumble dry low. No dry cleaning, no special care. Washing improves it — this is the rare blanket you should wash often.

Full 50×60 in (130×150 cm) · Queen 60×80 in (150×200 cm) · King 80×90 in (200×230 cm) · King XL 95×105 in (240×270 cm). Sizing runs generous — the Queen comfortably covers two sleepers with drape to spare.

You have 100 nights. If it isn't cooler than what it replaced, email us and send it back — washed, used, slept-in — for a full refund. No restocking fee, no store credit games.

Your coolest night is one layer away.
