SKIN SOOTHING: Silk has a naturally smooth surface that moves with skin instead of pulling on it, so skin holds its hydration and moves through the night without stress.
HAIR PROTECTION: The smooth surface of silk reduces the pulling and tugging that leads to breakage, frizz and tangles.
COOLING + CALMING: Naturally thermo-regulating silk keeps the surface cool and breathable through the night.
CLEAN SLEEP SURFACE: SILVADUR silver ions inhibit 99.9% of bacteria growth, keeping your pillowcase fresher between washes.
LASTING QUALITY: 25-momme, 6A grade mulberry silk, Oeko-Tex certified and built to hold its performance for years.
Why Silk for Skin + Hair
Cotton and traditional fabrics can absorb oils, skincare products and moisture while creating friction against skin and hair through the night. ZILK's ultra-smooth 25-momme silk reduces friction and absorbs less, helping skin retain its hydration and hair stay smoother with fewer tangles.
What Makes 25 Momme Exceptional
Momme measures silk's weight and quality. While 19 and 22 momme are common in bedding, ZILK uses 25 momme, a denser, smoother weight that creates a stronger fabric and keeps its silky finish wash after wash.
The Clean Sleep Surface
ZILK is infused with SILVADUR silver ions that inhibit 99.9% of bacteria growth on the fabric surface. Your pillowcase stays fresher between washes, giving you a cleaner, cooler sleep surface every night.
Silk's naturally smooth, dense weave absorbs less than cotton and holds up to hair products, skincare and daily wear without snagging or shedding fibers. The breathable, thermo-regulating surface also stays cool to the touch through the night for more comfortable rest.

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 ions are charged silver atoms that have been used for their cleanliness properties for centuries. When silver ions come into contact with bacteria on a fabric surface, they interrupt the bacteria's ability to function and multiply. ZILK silk is treated with SILVADUR, DuPont's silver-ion technology, which inhibits 99.9% of bacteria growth on the fabric surface and keeps your pillowcase 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 — the thickest and smoothest available — so it lasts longer and keeps its luxurious finish wash after wash.
