Cooler sleep, calmer skin, cleaner nights — a silk foundation for restorative rest.
Silk Fitted Sheet
For cooler sleep, smoother skin, and cleaner nights.
The ZILK Silk Fitted Sheet transforms your sleep surface into a restorative ritual. Its frictionless feel and thermo-regulating weave support deeper rest, helping skin stay calm and fresh while maintaining a cool, breathable environment all night.
SKIN SOOTHING: Reduces irritation and friction for sensitive or post-treatment skin.
COOLING + CALMING: Naturally thermo-regulating silk promotes deeper, more balanced sleep.
CLEAN SLEEP: Infused with silver ions to prevent bacteria, allergens, and odors.
BREATHABLE FIT: Elastic edges and deep pockets keep the sheet smooth and secure.
LASTING QUALITY: Premium 25-momme, 6A-grade OEKO-TEX® certified Mulberry silk designed for long-term durability and shine.
Why Silk Matters for Skin + Sleep
Cotton and synthetic blends absorb oils, skincare products, and moisture — creating friction and irritation that can disrupt skin health and sleep. ZILK’s tightly woven 25-momme silk helps regulate temperature and reduces irritation, keeping your skin calm and your sleep uninterrupted.
What Makes 25 Momme Exceptional
Momme measures silk’s weight and density. While 19mm and 22mm are standard, ZILK uses 25 momme — the densest, smoothest silk available. Its tighter weave lasts longer, maintaining its softness and strength wash after wash.
The Clean Sleep Surface
Infused with silver ions, ZILK silk resists bacteria and microbes (including mold and fungi), blocking up to 99.7% of growth** — keeping your sleep surface fresher and cleaner between washes.
Silk is naturally hypoallergenic, making ZILK ideal for sensitive skin and allergy-prone sleepers. Its breathable weave resists common allergens like dust mites while maintaining a cool, dry sleep surface that eases restlessness and supports deeper, restorative sleep.

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.
