25 Momme Mulberry Silk
LASH-FRIENDLY, LIGHT-BLOCKING AND ADJUSTABLE FOR DEEPER REST
A clinician's standard
Created by a dermatology PA who spent 15 years treating skin. 25-momme mulberry silk with silver-ion technology.
Lash-friendly: Sculpted cups lift silk away from lashes, reducing friction and pressure.
Total darkness: Cushioned contours block light completely for uninterrupted rest.
Comfort wrap band: Wide, adjustable band stays in place all night without pulling or tension.
Smoothing silk: 25-momme mulberry silk minimizes friction and creasing around the eye area overnight.
Clean sleep surface: Woven with SILVADUR™ silver-ion technology, stays fresher between washes.
Why Silk for Skin and Sleep
The skin around the eyes is some of the most delicate on the face. Unlike cotton or synthetics, silk glides smoothly against it, reducing friction and helping skin hold its hydration overnight.
The Role of Design
Sculpted 3D eye cups lift silk away from eyes and lashes. The wide comfort wrap distributes weight evenly across the head, so the mask stays in place without pressing.
What Makes 25-Momme Different
At 25 momme, the weave is denser and more durable than standard silk weights used in most masks. It resists stretching, thinning and pilling, so it holds its smoothness wash after wash.
Silk's smooth, dense weave is kind to skin around the eyes and doesn't shed fibers or snag on serums overnight. The breathable 25-momme weave is naturally thermo-regulating, staying cool against the skin through the night.

"After fifteen years of treating skin, I kept seeing the same pattern. Patients invested in their skin by day, then slept on a surface that worked against them all night. When I could not find a pillowcase that met my clinical standards, I made one. I designed ZILK to be the overnight foundation of your skin and hair routine, protecting what you invest in it by day and offering a calm, restorative surface to sleep on at night."
Elizabeth Cook, PA-C
Sleep is a big part of how skin and hair recover. Whatever ZILK piece you sleep on, the fabric is the same: 25-momme mulberry silk infused with SILVADUR silver ions. Smooth enough to glide against skin and hair, and clean enough to stay fresh between washes.
Every ZILK product is infused with Silvadur™ silver-ion treatment, from LANXESS. Designed to keep fabric cleaner between washes while staying gentle on skin.
Independently tested
ZILK silk was washed 20 times, then tested by SGS. The result: its silver-ion technology still inhibits the growth of bacteria on the fabric surface.
S. aureus and K. pneumoniae are the two standard bacteria used in textile testing.
Momme measures silk's weight and density. At 25-momme, the weave is tighter, the surface is smoother and the fabric holds its performance significantly longer than the 19-23 momme silk used by most brands. It's the difference between silk that feels good now and silk that keeps working for years.
ZILK Sleep uses only 6A grade mulberry silk, woven from the longest, most uniform fibers available. The result is exceptional softness, resistance to pilling and a surface that glides against skin and hair rather than catching on it.
Every ZILK Sleep fiber meets OEKO-TEX® STANDARD 100, the leading independent certification for textile safety. Tested against more than 1,000 potentially harmful substances and verified safe for daily skin contact.
Every ZILK piece is woven from 25-momme mulberry silk and infused with SILVADUR™ silver-ion technology, engineered for the surface your skin and hair rest on a third of your life. A cooler, smoother, quieter surface than what most people sleep on.
Yes, the cushioned contours and wide comfort wrap are designed to create complete darkness for uninterrupted rest.
Absolutely. The sculpted eye cups lift silk away from your lashes, preventing friction and pressure.
The Sculpted Mask includes contoured eye cups and a comfort wrap for a more custom, lash-friendly fit and total blackout.
Silver has been valued for its cleanliness properties since ancient times. Silver ions are charged silver atoms that interrupt the ability of bacteria on a fabric surface to multiply. ZILK silk features Silvadur™ technology from LANXESS to inhibit the growth of bacteria on the fabric surface, so your mask stays fresher between washes.
Hand wash or machine wash in a mesh bag on delicate cycle with a pH-neutral detergent; air dry flat.
