Why Silk for Skin + Hair
Cotton, satin and synthetic blends absorb oils, skincare products and moisture while creating friction that leads to sleep creases, irritation, hair breakage and frizz. ZILK’s ultra-smooth silk resists absorption and reduces friction, helping skin stay clearer and hair healthier with fewer tangles.
What Makes 25 Momme Exceptional
Momme measures silk’s weight and quality. While 19mm and 22mm are common, ZILK uses 25 momme — the densest, smoothest silk available. Its tighter weave creates a stronger fabric that lasts longer while keeping its silky finish wash after wash.
The Clean Sleep Surface
ZILK is infused with silver ions that resist bacteria and microbes (including mold and fungi), blocking up to 99.7% of growth*. Your pillow stays fresher between washes, giving you a cleaner, cooler sleep surface every night.
Silk is naturally hypoallergenic, making ZILK ideal for sensitive skin and allergy-prone sleepers. Unlike cotton, it resists common allergens including dust mites. The breathable, thermo-regulating weave also helps keep your sleep surface cool to the touch, easing restlessness and supporting deeper, more restorative sleep.

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

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 only 6A-grade Mulberry silk—the highest quality available. Woven from the longest, smoothest fibers, it delivers exceptional softness, strength, and purity. This superior grade creates a uniform weave that resists pilling and glides effortlessly against skin and hair, night after night.

- Free from toxins, irritants, and allergens
- Certified STANDARD 100 by OEKO-TEX®
The Science of Calm
NeuroSilk™ Technology for Mind–Body Restoration
Rest isn’t only about time spent sleeping, it’s about creating the conditions where your body and mind can let go.
ZILK’s NeuroSilk™ technology is inspired by the science of psychodermatology and neurocosmetics—fields that explore how emotions, stress and skin are connected. The goal is simple: support the brain and body as they shift into a calmer state.
Calming Sensory Cues: ZILK’s smooth, cooling sensation activates relaxation responses, signaling to your nervous system that it’s safe to slow down.
Less Friction, More Flow: When your skin and hair glide instead of tugging, it’s a small but powerful signal of ease.
Cleaner Rest, Clearer Mind: Silver ion infusion helps resist bacteria and odor, so your sleep surface feels fresher — reinforcing the ritual of calm.
