22 vs. 25 Momme Silk Pillowcases: Differences, Benefits & Is The Upgrade Worth It?

Key Takeaways

• 25 momme silk pillowcases pack in more silk than the 22 momme ones, which gives them a richer feel and makes them tougher in the long run.

• 22 momme silk still delivers top-notch softness and the skin-and-hair-loving benefits silk is known for, perfect if you’re new to the world of silk.

• Thanks to its tighter weave, 25 momme silk has a slightly glossier finish and can last 20–30% longer than its lighter counterpart.

• Both weights keep you comfy through the night, but 25 momme offers a little extra warmth when temperatures dip.

• At Mayfairsilk, we focus on premium Grade 6A Mulberry silk. Our pillowcases are made from luxurious 25 momme silk, and our sheets feature 22 momme silk, all with a distinctive matte finish that blends elegance with softness.

What Makes 22 & 25 Momme Silk Pillowcases Different

At a glance, 22 and 25 momme silk pillowcases might seem nearly identical; they’re both ultra-smooth, made from 100% mulberry silk, and ooze luxury. But once you sleep on them, the difference is in the details. 

The 25 momme feels just a bit weightier and more indulgent, with a silkier drape and extra staying power through washes and wear. It’s like upgrading from first class to a private suite; still silk, just next level.

The difference all comes down to momme, which is basically silk’s version of thread count. A higher momme means more silk is woven into every inch, giving you a thicker, more durable fabric that still feels heavenly against your skin.

What Does "Momme" Mean in Silk?

Momme (pronounced “moh-mee”) is a Japanese unit of measurement that tells you how much silk is in a piece of fabric. One momme equals 4.340 grams per square meter. So the higher the number, the denser and stronger the silk.

19 momme is lightweight and more budget-friendly, but it wears out faster. 22 momme strikes a great balance between softness and strength. And 25 momme? That’s the gold standard: thicker, more luxurious, and built to last.

Key Differences: 22 Momme vs 25 Momme Silk Pillowcases

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 fibers, 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 can last 5–10 years with nightly use. Use it occasionally or for guests, and you’ll get even more mileage. It’s the perfect blend of comfort, care, and value, especially if you're just starting your silk journey.

25 Momme Silk Pillowcase Benefits

Enhanced Durability & Longevity

If you're in it for the long haul, 25 momme silk is your go-to. It's thicker, tougher, and just built to last. With regular use and a little care, it can easily hold up for 5–10 years or more, often outlasting lighter silk options by a good margin. 

You’ll really 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 cozy 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 elevates 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 cozy 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.

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.

Does Mayfairsilk offer a range of silk products beyond pillowcases?

We sure do! In addition to our 25 momme pillowcases, we offer 22 momme bed sheets and duvet sets, silk eye masks, scrunchies, and hair ties—all made for comfort, elegance, and long-term use.
