22 vs. 25 Momme Silk Pillowcases: Differences, Benefits & Is The Upgrade Worth It?
Key Takeaways
-
The choice between 22 and 25 momme silk pillowcases comes down to how heavy, durable, and breathable you want the fabric against your skin each night.
-
Most shoppers default to whichever weight is cheaper or more readily available, but that often means settling for a feel that does not match how you actually sleep.
-
Mayfairsilk crafts 25 momme pillowcases and 22 momme sheets in Grade 6A mulberry silk, so you can match each piece to its job rather than picking a single weight for the whole bed.
-
A 25 momme pillowcase weaves around 750 threads per inch versus roughly 600 in 22 momme, which is what gives the heavier weight its denser drape and longer wear life.
-
Mayfairsilk's 25 momme pillowcase pairs that high-density weave with a signature matte finish, reducing friction on hair and skin while regulating temperature through the night.
22 vs 25 Momme Silk Pillowcases: Quick Comparison
The short answer: a 22 momme silk pillowcase sleeps lighter, cooler, and at a friendlier price point, while a 25 momme silk pillowcase weaves more silk per square metre for a denser drape, richer sheen, and longer wear life. Mayfairsilk crafts its pillowcases at 25 momme and its sheets at 22 momme in Grade 6A mulberry silk, so the right choice depends on how warm you sleep, how often you wash, and whether you want the heavier hand-feel under your face or across the whole bed.
Silk weight is one of those details that sounds technical but shapes every minute you spend in bed, and getting it right is the difference between a pillowcase you tolerate and one you look forward to. The sections below break down what each weight actually does for your hair, skin, and sleep, so you can tell which one is worth it for you.

22 Momme Silk Pillowcase Benefits
Softness & Comfort Level
22 momme silk feels incredibly soft, like sleeping on a cloud. It’s light, smooth, and adapts to your body temperature almost instantly. The silk’s natural proteins give it that signature glide that synthetic fabrics just can’t match.
Snuggling up with a 22 momme silk pillowcase gives cloud-like softness and a natural glide that feels effortlessly luxurious.
Breathability & Temperature Regulation
This weight of silk is breathable and great at keeping your temperature just right all night. It wicks away moisture and allows airflow between the fibres, making it ideal if you tend to overheat or live in a warmer climate. You’ll stay cool and comfortable without constantly flipping the pillow.
Hair & Skin Benefits
Silk reduces friction, and 22 momme delivers those beauty perks effectively. Hair glides across the surface with less breakage and frizz, while your skin is spared the tugging and creasing that comes with cotton. Plus, it doesn’t soak up your expensive night cream, and it’s naturally hypoallergenic, which is a win for sensitive skin.
Typical Lifespan with Proper Care
With gentle washing and air drying, a 22 momme pillowcase typically holds up for 2 to 4 years of nightly use before the surface starts to dull. Use it occasionally or for guests and you will get noticeably more mileage. It is the perfect blend of comfort, care, and value, especially if you are just starting out with silk.
25 Momme Silk Pillowcase Benefits
Enhanced Durability & Longevity
If you are in it for the long haul, a 25 momme silk pillowcase is your go-to. It is thicker, tougher, and built to last. With regular use and a little care, it typically holds its smooth surface for 2 to 4 years of nightly use, often outlasting lighter silk options at the edges and seams where wear shows first.
You will notice the difference over time, especially around the edges where wear and tear usually show first. The best part: it keeps its smooth texture and elegant feel wash after wash.
Luxurious Feel & Appearance
There’s something instantly indulgent about 25 momme silk. It has a slightly weightier drape that feels cosy and grounding without being heavy. Many people say it stays in place better while you sleep, and let’s be honest, that “tucked-in luxury” feel is half the fun.
Visually, it has a deeper, more luminous sheen that really lifts your bed’s look. It’s the kind of fabric that looks as good as it feels, and it keeps that rich, smooth texture much longer than lighter silk.
With its rich sheen and plush drape, a 25 momme silk pillowcase adds weight and luxury to your sleep setup.
Improved Insulation Properties
While all silk is great for regulating temperature, 25 momme takes it a step further with a touch more warmth. That extra density helps retain just enough heat to keep you comfortable on cooler nights without making you overheat. So no matter if it’s summer or winter, you’re sleeping in comfort and style year-round.
Is the Upgrade to 25 Momme Worth It?
If you're all about indulging in the finer things, then yes, upgrading to 25 momme silk is totally worth it. It's the go-to choice for anyone who wants top-tier durability, a richer feel, and a pillowcase that holds up beautifully over time. It’s especially great if you’ve got sensitive skin or hair, or if you live somewhere cooler and love that touch of cosy warmth when you hit the pillow.
But if you prefer something a bit lighter and more fluid, 22 momme might be your perfect match. It still delivers all the signature silk perks: softness, breathability, and beauty benefits, just with a slightly breezier feel and a friendlier price tag.
The Smarter Way to Mix 22 and 25 Momme Silk
Mayfairsilk’s premium bedding blends soft matte elegance with skin-loving comfort, bringing effortless luxury to every night's rest.
Choosing between 22 and 25 momme is less about picking a winner and more about matching weight to job: lighter and breezier for full-bed sheets, denser and more durable for the pillowcase that takes nightly contact with your face and hair. Either way, the grade and finish of the silk itself shapes the experience far more than the momme number alone.
That is where Mayfairsilk comes in. We craft our pillowcases at 25 momme and our sheet sets at 22 momme from Grade 6A mulberry silk with a signature matte finish, so each piece is the best version of itself and works as a set without compromise.

Frequently Asked Questions (FAQ)
How much longer does a 25 momme silk pillowcase last compared to 22 momme?
About 6 to 12 months longer with regular use. That extra silk makes it tougher and more resistant to wear and tear, especially after the one-year mark.
Can I machine wash both 22 and 25 momme silk pillowcases?
Yes, just treat them gently. Use a mesh bag, cold water, and silk-friendly detergent. 25 momme handles the spin cycle a bit better if you wash often.
Is 25 momme silk too heavy for summer use?
Not at all. It’s slightly thicker, but still breathable and cool. Silk naturally adjusts to your body temperature, so it works year-round.
Do 25 momme silk pillowcases wrinkle less than 22 momme ones?
They do! The denser weave helps them bounce back quicker after sleep or washing. But with the right care, 22 momme stays smooth, too.
