25 Momme Mulberry Silk
FOR DEEPER, DARKER, LASH-FRIENDLY 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.
Total darkness: Cushioned contours, complete blackout.
Flexible fit: Silk-covered elastic, secure and gentle.
Smoothing silk: 25-momme silk, glides against skin.
Cleaner surface: SILVADUR™ silver-ion, stays fresher between washes.
Why Sculpted Design Matters
Most sleep masks press directly against lashes and eyelids, which can feel uncomfortable overnight. Our sculpted 3D eye cups lift silk away from the eye area, giving eyes space to rest and lashes room to settle without pressure.
Why Silk for Skin and Sleep
Synthetic and cotton masks create friction and absorb overnight skincare. ZILK's 25-momme mulberry silk moves smoothly against skin through the night, so serums and products stay on your skin instead of the fabric.
The Clean Sleep Surface
ZILK masks are infused with Silvadur™ silver-ion technology, from LANXESS, designed to resist odors and keep fabric fresher between washes.
Silk's smooth, dense weave is kind to skin around the eyes and doesn't shed fibers or snag on serums overnight. The thermo-regulating 25-momme weave keeps the mask cool against the skin through the night, no matter how you sleep.
Suitable for: All skin types
Treatment: Silver-ion infusion

"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.
The contoured design and cushioned silk panels block most light, helping you fall asleep faster and stay asleep longer, whether at home or while traveling.
The Sculpted Sleep Mask with Flex Band is our most lightweight, travel-friendly option. It features contoured eye cups and a flexible elastic band for gentle, adaptive comfort. The Comfort Wrap and Deep Restoration masks offer a fuller, cocooning fit for total blackout and a more secure feel.
Hand wash or machine wash in a mesh bag on a delicate cycle with a pH-neutral detergent. Do not wring. Gently press out excess water with a towel and air dry flat to preserve the silk’s natural softness and shape.
