Why Silk Matters for Skin + Sleep
Unlike cotton or synthetics, silk doesn’t absorb moisture or skincare — helping your body maintain hydration and balance while you rest. ZILK’s tightly woven 25-momme silk reduces friction and irritation, supporting smoother skin and calmer sleep.
What Makes 25 Momme Exceptional
Momme measures silk’s weight and density. ZILK uses 25 momme — the densest and most durable silk available — for a stronger, smoother, and longer-lasting finish.
The Clean Sleep Surface
ZILK’s silver-ion infusion blocks up to 99.7% of bacterial growth*, helping your duvet stay fresher longer between washes and creating a cleaner, more hygienic sleep environment.
Silk is naturally hypoallergenic, making ZILK ideal for sensitive skin and allergy-prone sleepers. Its breathable weave resists common allergens like dust mites and helps maintain a comfortable, temperature-balanced environment throughout 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 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.
