Discover why 22-momme silk outperforms 19-momme for sleep masks. Learn how silk weight affects durability, light blocking, and luxury feel. SunnySass uses only 6A grade 22-momme mulberry silk.
When Shopping for a Silk Sleep Mask, You'll Encounter Terms Like "19-Momme" and "22-Momme"
Most consumers gloss over these numbers, but they're the single most important factor determining whether your silk mask will last months or years.
At SunnySass, we've made a non-negotiable commitment: every silk eye mask in our collection uses 22-momme 6A grade mulberry silk—the highest standard in the industry.
Here's why that matters.
What is Momme?
Momme (pronounced "mummy") is a traditional Japanese unit of weight specifically used for silk fabrics. One momme equals approximately 4.34 grams per square meter of silk.
The Math
-
19 momme = ~82.5 g/m² of silk
-
22 momme = ~95.5 g/m² of silk
-
Difference: 20% more silk fiber in 22-momme fabric
Think of it as thread count in cotton sheets—higher numbers mean denser, more substantial fabric. But unlike thread count (which can be manipulated), momme is a direct measurement of silk weight. You can't fake it.
Why 19-Momme Falls Short for Eye Masks
19-momme silk is perfectly adequate for scarves or lightweight lingerie. But an eye mask faces unique demands.
Problems with 19-Momme for Sleep Masks
Light Penetration Thinner fabric allows more light to pass through, disrupting sleep quality.
Durability: Less fiber = faster wear. Expect pilling and thinning after 50-80 washes.
Shape Retention: More prone to stretching and losing its contoured fit over time.
Luxury Feel: Noticeably thinner and less "buttery" against skin.
The SunnySass Standard: 22-Momme 6A Grade Mulberry Silk
At SunnySass, we don't compromise. Our silk eye masks are crafted from:
-
22-momme weight for superior durability and light blocking
-
6A grade mulberry silk—the highest quality classification
-
100% pure mulberry silk from trusted suppliers in Suzhou, China
-
Creamy, buttery texture that feels luxurious against the skin
-
Enhanced opacity for true 100% blackout performance
Why 22-Momme Matters for Light Blocking
The additional 20% silk fiber creates a denser weave that naturally blocks more light. Combined with our ergonomic nose contour design, this ensures zero light leakage—even in bright environments like airplanes or hotel rooms.
