Sleep Through The Night Again
Cotton holds onto moisture. Silk lets it go. That difference matters at 3AM.
Sleep Through The Night Again
Cotton holds onto moisture. Silk lets it go. That difference matters at 3AM.
Breathes With Your Body
Silk's natural structure allows air to circulate and moisture to evaporate, so you're not lying in damp fabric when you wake.
Reduces the Hot-Cold Cycle
Unlike cotton that traps sweat and turns cold, silk helps minimize those jarring temperature swings that jolt you awake.
22 Momme for Nightly Use
The ideal weight for durability and breathability. Dense enough to hold up to frequent washing, light enough to let your body regulate.
Sleep You Won't Dread
Temperature-responsive and gentle against warm skin — designed for women who need comfort during the night.

When you wake up drenched, your body is trying to cool itself down.
But if your pillowcase traps that moisture against your skin, you end up soaking wet, then freezing when the sweat turns cold.
It's not just uncomfortable. It's a cycle that keeps repeating, night after night.
This is why the fabric you sleep on matters more than you might think.

Add to BagFrequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
Will this actually help if I sweat a lot at night?
+
We can't promise it will stop night sweats — that's a body process, and we're not a medical product. What we can say is that silk behaves differently than cotton when it comes to moisture. Cotton absorbs sweat and holds it against your skin, which can leave you damp and then cold. Silk allows moisture to evaporate, so you're less likely to wake up in that clammy, stuck-to-the-pillow feeling.
Is Zentropic™ easy to wash?
+
Yes! Hand wash, or machine wash cold in delicate cycle, separately from other items.
Hang dry, or cold air machine dry.
Isn't satin the same thing?
+
No, and this is a common misconception. Most satin pillowcases are made from polyester, which is a synthetic fabric. It looks smooth, but it doesn't breathe the same way natural silk does. Polyester can actually trap heat and doesn't wick moisture effectively. Our pillowcase is 100% mulberry silk, a natural protein fiber with breathability and temperature-responsive properties that polyester simply can't replicate.
What if it doesn't work for me?
+
We understand this might feel like a leap. That's why we offer a 60-day return policy return policy with hassle-free returns. If it's not making your nights better, send it back. We'd rather you try it and know than keep struggling with what you're currently using.
What Is 22 Momme Silk?
+
“Momme” (mm) is the unit used to measure the weight and density of silk fabric. The higher the momme, the heavier and more substantial the silk feels.
At 22 momme, Zentropic™ sits at the higher end of the premium silk category. The denser weave offers enhanced durability, a richer hand feel, and a more substantial drape, while still remaining smooth, breathable, and gentle against the skin.
Compared to traditional cotton pillowcases and the lighter 19 momme silk, 22 momme silk is smoother in texture, more moisture-conscious, more temperature responsive and denser and more refined in weave.
How long will they last?
+
With proper care, a 22 momme Mulberry silk pillowcase will last for years.
The 22 momme weight offers a durable, tightly woven structure designed for regular use and washing, without feeling heavy.
For best results, wash cold on a delicate cycle with mild detergent and air dry.
What is your shipping policy?
+
Orders are processed within 1-2 business days and typically arrive within 5–12 business days. International orders typically arrive within 7-15 business days.
What is your return policy?
+
We offer a 60-day return policy. If you're not satisfied with your purchase, you can return it within 60 days for a full refund or exchange. Returns & Refunds
