25 Momme Mulberry Silk

A light-blocking silk ritual for deeper, restorative rest.
LIGHT BLOCKING: Comfortably shields light for deeper, uninterrupted rest.
SKIN SOOTHING: Gentle silk reduces friction and surface irritation through the night.
COOLING + CALMING: Breathable, thermo-regulating silk eases restlessness and keeps the surface cool.
CLEAN SLEEP SURFACE: SILVADUR silver ions inhibit 99.9% of bacteria growth, keeping your mask fresher between washes.
LASTING QUALITY: Premium 25-momme Mulberry silk that stays smooth wash after wash.
Why Silk for Skin + Sleep
Cotton and synthetic mask fabrics can absorb oils, moisture and skincare products while creating friction against skin through the night. ZILK's ultra-smooth silk absorbs less and reduces friction, helping skin retain its hydration and minimizing overnight creases.
What Makes 25 Momme Exceptional
Most silk masks use lighter 19 to 22 momme silk. ZILK uses 25 momme, a denser and smoother weight that creates a stronger fabric and keeps its silky finish night after night.
The Clean Sleep Surface
ZILK masks are infused with SILVADUR silver ions that inhibit 99.9% of bacteria growth on the fabric surface, keeping your mask fresher between washes.
Silk's naturally smooth, dense weave is gentle against skin and holds up to skincare, serums and daily wear without snagging. The breathable, thermo-regulating surface keeps the mask cool against the skin for more comfortable rest through the night.

ENGINEERED FOR ENDURANCE
25 MOMME SILK
The higher the momme, the tighter the weave, and the longer it lasts. ZILK uses 25 momme Mulberry silk, the highest density available, for a smoother surface that protects hair and skin while maintaining its beauty for years of nightly use.
THE HIGHEST GRADE MULBERRY SILK
6A Silk Quality
ZILK uses 6A-grade mulberry silk, the top tier of the standard silk grading system. 6A silk is woven from the longest and smoothest fibers, giving the fabric a uniform weave that resists pilling and glides against skin and hair night after night.

Cleaner Rest: SILVADUR silver ions inhibit 99.9% of bacteria growth, keeping your sleep surface fresher between washes.
Frequently Asked Questions
