You asked for it. It’s here.

The duvet cover version of our 365 Blanket — made from the same breathable, 100% natural muslin cotton you already love. Interior ties to keep your insert in place. Hidden zipper closure (because life is too short for buttons or ties).

Designed to create a soft, breathable layer between you and your duvet insert — so you stay cozy, not sweaty.

Made to fit your life (and your bed)

Designed to fit standard duvet inserts — no guesswork, no replacements needed.

Upgrade your sleep without replacing everything.

You get the same breathable, temperature-regulating benefits of the 365 Blanket — now in a duvet cover designed for your existing insert.

Care

We do NOT recommend using fabric softener, dryer sheets, or chemical-based detergents.
These can coat the fibers and cause the fabric to feel stiff, reducing breathability.
