300 thread count long-staple organic cotton sateen, cut generously so it still tucks after it shrinks.
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.
The color is the cotton’s own, a natural warm off-white rather than the blue-white that comes out of a
bleaching and optical-brightener process. Next to bright white bedding it reads as cream.
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.
A flat sheet is the layer that actually touches you if you sleep under a duvet, so it is worth more than the afterthought it usually gets.
Sizes run Twin, Full, Queen and King.
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.
Sheets are the largest area of fabric against you all night, so the finishing chemistry matters more here than on
anything else you buy for the bed.
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 these sit against the sheets you have owned before.
Against a 1000 thread count sheet
Counts far above 300 usually come from multi-ply yarn counted more than once, which means thinner strands twisted
together to inflate the number. The cloth is heavier and less breathable, not better. Three hundred in single-ply
long-staple cotton is the honest version of that number.
Against a wrinkle-free sheet
Wrinkle-free almost always means a resin finish, and the resin in question is usually formaldehyde-based. That is
exactly the category GOTS exists to rule out. These wrinkle.
Against microfiber
Microfiber is polyester. It is cheap and it does not breathe, so body moisture stays against your skin instead of
moving through the cloth.
"Made in" labels only reveal a fraction of a product's journey. Supply chains are complex, involving multiple stages across different countries.

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.
