THE SURFACE THAT SHAPES SKIN AND HAIR

WHY SILK MATTERS

Your pillowcase is part of your skincare routine, whether you think of it that way or not. ZILK's 25-momme, 6A grade mulberry silk glides over skin to reduce friction, hold hydration where it belongs, and treat hair more gently than cotton.

ZILK is also infused with SILVADUR™, DuPont's patented silver-ion technology, designed to resist odors and keep fabric fresher between washes.

THE SCIENCE OF SILK

WHAT MAKES ZILK DIFFERENT

Most silk pillowcases use 19 to 22 momme. ZILK uses 25-momme, 6A grade mulberry silk, the densest weight on the market for durability and smoothness. The longer silk fibers create a stronger, more uniform weave that holds its performance wash after wash.

Oeko-Tex® and bluesign® certified, tested against over 1,000 harmful substances.

ROOTED IN SILK SCIENCE

Silver-Ion Technology

All ZILK products are infused with SILVADUR™, DuPont's patented silver-ion technology, designed to keep fabric cleaner between washes while staying gentle on skin.

  • SILVADUR™ silver-ion treatment
