SMOOTHER SKIN: Silk glides where cotton drags. Less friction overnight for smoother, softer skin by morning
GENTLE ON HAIR: Less friction means less breakage, less frizz and fewer tangles
LIGHT BLOCKING: Silk sleep mask shields light completely for uninterrupted rest
COOLING + CALMING: Breathable, temperature-regulating silk that helps your body settle into rest
CLEAN SLEEP SURFACE: SILVADUR™ silver-ion infused across every piece in the kit, stays fresher between washes

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 piece in the ZILK sleep kit is infused with SILVADUR™, DuPont's patented silver-ion technology, designed to resist odors and keep silk 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.

Product information

Ritual of Restoration

SMOOTHER NIGHTS, CLEANER SLEEP

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.

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

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.

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 ZILK Sleep Kit items?

Pillowcase + scrunchies can be hand or machine washed in a mesh bag on delicate, with pH-neutral detergent. Sleep mask should be hand washed for best results. Do not wring. Air dry flat or hang.

What are silver ions and why are they used in ZILK products?

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 ZILK Sleep Kit 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.
