Organic Supima Duvet Cover FAQs

What is a duvet cover?

A duvet cover is a removable shell that wraps around your duvet insert, similar to how a pillowcase wraps around a pillow. It protects your insert and makes it easy to refresh your bedding without washing the entire duvet. Simply remove, wash, and replace.

What makes Supima cotton different from regular cotton?

Supima cotton represents less than 1% of the world's cotton and is prized for its extra-long staple fibers. These fibers create a smoother, stronger yarn that resists pilling and maintains softness over time — resulting in a duvet cover that feels noticeably more refined than standard cotton and holds up wash after wash.

Does this duvet cover have corner ties?

Yes. This duvet cover includes built-in corner ties to help keep your insert securely in place. You can attach the ties to the loops on your duvet to prevent shifting and bunching, so your bed stays smooth and comfortable.

Is this Supima cotton certified organic?

Yes. Supima refers to the quality of the fiber — specifically extra-long staple cotton grown in the U.S. — but not how it's farmed. Our Supima duvet cover is GOTS-certified organic, meaning the cotton was grown without synthetic pesticides or fertilizers and processed according to strict environmental and social standards.
