SMOOTHER SKIN AND HAIR: Reduces friction overnight
LESS FRIZZ, LESS BREAKAGE: Helps minimize tangles and damage
CLEANER SLEEP: Woven with SILVADUR™ silver-ion technology
NATURALLY COOL: Temperature regulating mulberry silk
BUILT TO LAST: 25-momme, 6A grade, Oeko-Tex® certified

Why Silk for Skin + Hair
Cotton absorbs oils, moisture and skincare products, creating friction that can cause sleep creases, breakage and frizz. ZILK absorbs less and reduces friction, so your products stay where they belong and your hair wakes with fewer tangles.

Why 25-Momme?
Momme measures silk's weight and density. Most silk pillowcases use 19 to 22 momme. ZILK uses 25 momme, which means a tighter weave, smoother surface and a fabric that holds its performance wash after wash.

The Clean Sleep Surface
Every ZILK pillowcase is infused with SILVADUR™, DuPont's patented silver-ion technology, designed to resist odors and keep fabric fresher between washes.

Silk's dense, smooth weave is kind to skin and leaves no fiber shedding or snags behind. The thermo-regulating surface keeps the pillowcase cool and breathable, so the temperature stays comfortable whether you run warm or cool at night.

Suitable for: All skin types
Treatment: Silver-ion infusion
Fabric: 100% 25-momme 6A grade Mulberry silk
Closure: Hidden zipper
Fitting: When in doubt, size up. A little extra space won’t change the benefits.
Certification: Oeko-Tex® certified, responsibly made, non-toxic
Care: Machine Washable

Product information

Elizabeth Cook, Founder of ZILK Sleep

Made by a clinician

Elizabeth Cook

Physician Assistant  ·  Aesthetic Expert

Elizabeth designed ZILK for the patients she sees every day.

"For years I told patients to sleep on silk to protect their skin and hair. When I could not find a pillowcase that met my clinical standards, I made one. ZILK is what I recommend to my own patients, and what I sleep on every night."

Who It's For

The pillowcase that protects your routine

If you spend on skincare, wake to creased cheeks, or notice friction wearing on your hair, your pillowcase could be doing more damage than you think. ZILK is the surface that protects what you've already invested in.

  • You wake with sleep lines, pillow creases, or a flattened blowout
  • You invest in your skincare, lashes, brows, and hair
  • Your hair is color-treated, fine, curly, or prone to breakage
  • You wake up with frizz, flyaways, or hair that needs restyling
  • You sleep hot and want a surface that stays cool through the night

INSIDE EVERY ZILK PIECE

Silver Ion Technology

Every ZILK product is infused with SILVADUR™, DuPont's patented silver-ion treatment. Designed to keep fabric cleaner between washes while staying gentle on skin.

  • SILVADUR™ silver-ion treatment
  • Fresher fabric, wash after wash
  • Oeko-Tex® certified for textile safety
Graphic explaining why 25 momme silk is higher quality, comparing Zilk 25 momme weave to lower momme silk from other brands and noting durability differences

ENGINEERED FOR ENDURANCE

25 MOMME SILK

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.

HIGH GRADE MULBERRY SILK

6A Silk Quality

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.

Silk fabric with OEKO-TEX certification label and text about product safety.

INDEPENDENTLY VERIFIED SAFETY

OEKO-TEX® Certified Clean Sleep

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.

  • Independently tested, not self-certified
  • Safe for sensitive skin and hair
  • Free from toxins, irritants and allergens

THE SCIENCE BEHIND THE FEEL

Silk, Engineered for Sleep

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.

  • Cool, smooth contact against skin all night
  • Less friction means less pulling on skin and hair
  • SILVADUR™ silver-ion infused, stays fresher between washes

Frequently Asked Questions

How do I wash my silk pillowcase?

To preserve the natural softness and luster of your silk, hand wash in cold or lukewarm water with a pH-neutral detergent. If you prefer machine washing, place it in a mesh laundry bag and wash on the delicate cycle with like colors. Do not wring. Gently press out excess water with a towel, then hang or lay flat to dry. If needed, use a cool iron or steamer on the reverse side.
What are silver ions and why are they used in ZILK pillowcases?

Silver has been valued for its cleanliness properties since ancient times. ZILK silk is treated with SILVADUR™, the silver-ion technology developed by DuPont, designed to resist odors and keep fabric fresher between washes.
How long will my pillowcase last?

With proper care, ZILK’s 25 momme silk maintains its smoothness and durability for years of nightly use.
What is a momme?

Momme (pronounced "mo-may") is the unit used to measure silk's weight and quality. A higher momme means a denser weave and more durable fabric. While many silk pillowcases are made with 19 or 22 momme silk, ZILK uses 25 momme, a denser and smoother weight that holds its finish wash after wash.
