300 thread count long-staple organic cotton sateen, the same cloth on both faces.
Sateen is a four-over-one float, so four out of every five threads sit on the surface instead of being tied down into the weave. That is what gives it the low sheen and the cool slide, and because it is structural it survives washing. The count is 300, which sits near the top of what a square inch of cotton will physically hold before the yarn has to be thinned to fit.
The cotton is long-staple, so each fiber is long enough to spin into a fine even yarn without the short ends that make cheaper cotton pill and go rough.
Most duvet covers pair a presentable face fabric with a cheaper backing, so the side you sleep against is the side
the label never mentions. This is one fabric front and reverse. Flip the cover inside out and you cannot tell which
side was meant to show.
How it’s made
Cut and sewn by hand in New Jersey, at the same workshop that has been making our pillows and duvets since 1981. The workshop holds the GOTS certification and is audited on site every year.
It closes with a zipper running along one side, so the insert goes in and the cover comes off for washing without
fighting a row of buttons.
Sizes: Twin 72 by 90 inches, Queen 92 by 96, King 96 by 110. Cut to fit our duvets and standard comforters in the
same size range.
Global Organic Textile Standard (GOTS) license GOTS-10229, issued by Oregon Tilth, and the license number is public so you can look it up rather than take our word for it.
The certification covers the sateen through every stage that touches it, from the fiber to the finished cloth, and
the workshop that cuts and sews it holds the license too.
What this means at your bedside
GOTS rules out chlorine bleaching, formaldehyde softeners, flame retardant chemicals and synthetic finishes across the whole supply chain. No optical brighteners either, which is why the color is the cotton’s own rather than the blue-white you get from a dye house. It opens odorless and stays that way.

Where this sits against the covers you have owned before.
Against a softened-finish cover
Most covers arrive wonderful and go ordinary by the second wash, because the softness was a silicone or resin finish
applied at the end. It rinses out. This one gets its hand from the fiber and the weave, so it does the opposite and
keeps softening.
Against a cotton-polyester blend
Blends resist wrinkling because the polyester holds a shape, and they trap heat for the same reason. Pure cotton
creases and breathes. If you want a bed that never looks rumpled, this is the wrong cover.
Against linen
Linen is cooler and coarser and takes years to break in. Sateen is smooth from the first night. It is a texture
preference more than a quality difference.
"Made in" labels only reveal a fraction of a product's journey. Supply chains are complex, involving multiple stages across different countries. As we strive for greater transparency, we outline each step of production and the country where it takes place. This information relates to the main material/s used.

Cold wash, low tumble, and it gets better.
Machine wash cold on a gentle cycle and tumble dry on low. Line drying is better still if you have somewhere to hang it, and it is what the workshop recommends. Cotton sateen softens every time it goes through the wash, so the piece you own in a year will feel better than the one that arrived.
Skip the fabric softener and the dryer sheets. Both work by leaving a waxy coating on the fibers, which is the opposite of what you want on a cloth chosen for its breathability, and over time it dulls the sateen’s sheen. Skip chlorine bleach too, which weakens cotton and will pull the natural color unevenly.
Expect a little shrinkage on the first wash, which is normal for unresined cotton and is already accounted for in the cut. Wash before first use if you like; there is no finish to rinse out, but it takes the packing creases with it.
