How our organic cotton duvet covers are made
Every Or & Zon duvet cover is woven in a family-run mill in northern Portugal using traditional looms. We use long-staple organic cotton (for percale and sateen) and 100% French flax (for linen). Long fibers are why our duvet covers feel smooth without inflated thread counts. All bedding is Oeko-Tex® Standard 100 certified, meaning every component has been tested against 100+ harmful substances.

Frequently asked questions about duvet covers
What is a duvet cover?
A duvet cover is a removable, washable outer shell that protects a duvet — the inner insert filled with down or alternative fill. Unlike a comforter (which combines fill and cover into one piece), a duvet cover slides off for easy machine washing, which is why duvet covers are the go-to choice for everyday bedding.
Duvet cover vs comforter — what's the difference?
A comforter is a single all-in-one piece that's harder to wash. A duvet system is two pieces: an inner duvet (the fill) plus a duvet cover (the washable shell). The cover protects the duvet and lets you switch styles seasonally without buying new bedding.
How do I put on a duvet cover?
Turn the cover inside out. Reach inside, grip the two top corners, and clip them to the duvet's top corners. Then flip the cover right-side out by pulling it down over the duvet. Button or tie the bottom closed.
Are organic duvet covers worth it?
Yes if you have sensitive skin, allergies, or care about chemical exposure overnight. Oeko-Tex® certification verifies the fabric is free from 100+ harmful substances.
