Silk Sleep Masks

We use 100% pure 22-momme 6A Mulberry silk, OEKO-TEX® certified for purity and safety. “Momme” is the measure of silk’s weight and density —22-momme is considered the gold standard for luxury bedding and sleepwear, offering the perfect balance of softness, durability and shine.

Our silk helps to reduce friction on skin and hair, minimizing tangles, frizz, and sleep creases. It’s temperature-regulating, keeping you cool in summer and warm in winter. Naturally hypoallergenic and moisturizing, it supports healthy skin, hair, and sleep — for adults and children alike.

Unlike cotton, which absorbs moisture and can dry out skin and hair, Mulberry silk naturally retains hydration. And while satin is a synthetic weave, silk is a natural fiber, breathable and gentle on even the most sensitive skin. The result: a smoother complexion, shinier hair, and more restful sleep.

Hand-wash or machine-wash on delicate with cold water and pH-neutral detergent. Air-dry or tumble-dry on low. Avoid bleach, fabric softeners, and harsh chemicals.
