WHAT'S IN THE BOX
CARE
- Use a duvet cover and spot clean only with a gentle, silk-friendly detergent, then air dry completely.
- No machine washing or dry cleaning.
- Every few weeks, air it out away from direct sun, or tumble on low for about 15 minutes to restore its loft.
- Between seasons, store it loosely in its cotton storage bag.

Always the right temperature
Silk fibers naturally allow air and moisture to move freely, so your body stays at a comfortable temperature through the night.
No overheating, no waking up too hot. Just restful, uninterrupted sleep.
Just like a hug
Silk fill creates a soft, fluid drape that naturally follows the shape of your body. It settles around you like a hug, light enough to barely feel, warm enough to never want to leave.
Made to be easy
Labeled sides mean you always know which way it goes, and 8 interior ties keep it in place inside your cover. Changing your duvet cover takes seconds, not guesswork.
Warmer when you need it
Use the Lightweight on its own for spring and summer, or attach it to the Classic Silk Duvet with the built-in clips for extra warmth on colder nights. Two duvets, every season covered.
Compact and easy to store
When the season changes, fold it loosely into the included cotton storage bag and tuck it away. No compression, no bulk, no fuss.
