Why Silk for Skin and 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 minimises friction, helping skin retain its hydration and reducing overnight creases.

What Makes 25-Momme Different
Most silk masks are woven at 19 to 22 momme. ZILK uses 25, a denser and smoother weight that creates a stronger fabric and holds its silky finish night after night.

The Clean Sleep Surface
ZILK masks are woven with SILVADUR™, DuPont's patented silver-ion technology, designed to resist odours and keep silk 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.

Treatment: Silver-ion infusion
Fabric: 100% 25-momme 6A grade Mulberry silk

ENGINEERED FOR ENDURANCE

25 MOMME SILK

Most silk pillowcases are woven at 19 to 22 momme. ZILK uses 25. The difference is a tighter weave and a smoother surface that holds its beauty through years of washes.

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.
