19 vs 22 Momme Silk Sleep Mask: Which Silk Grade Is Better in 2026?

For a sleep mask, 22 momme isn’t automatically better than 19 momme. It’s the denser silk, with about 16% more silk per square meter, so choose it for the plushest feel on a mask you wear every night, and choose 19 momme for a lighter, more affordable mask.

Both are genuine mulberry silk. On a mask, the shape, filling and strap decide light blocking and comfort more than the silk weight does. Below: what the numbers measure, how the grades differ on your face, which grade suits your situation, and a side-by-side table of nine 19- and 22-momme masks. For our overall favorites, see the best silk sleep masks roundup.

19 vs 22 Momme: The Short Answer for Sleep Masks

22 momme is the heavier silk: about 95.5 g/m² against roughly 82.5 g/m² for 19 momme. 19 momme is lighter and usually sits in a more affordable tier. Neither is a compromise on the material itself.

The gap matters less on a mask than on a pillowcase. On a pillowcase, the silk is essentially the whole product. On a sleep mask, it’s the outer layer of a small, often padded object — and the filling, contour and strap do most of the work of blocking light and staying comfortable all night.

Rule of thumb: choose 22 momme if you want the plushest feel and plan to wear the mask every night. Choose 19 momme if you want a lighter mask on an entry-level budget. Then focus on shape, filling and strap, which our guide to choosing a silk sleep mask covers in detail.

What the Numbers Mean (in 30 Seconds)

Momme is a weight measure. It’s the weight in pounds of a piece of silk 45 inches wide and 100 yards long: if that piece weighs 19 lb, the fabric is 19 momme; if it weighs 22 lb, it’s 22 momme. Labels often shorten it to “mm,” so 22mm and 22 momme mean the same thing.

In metric terms, 1 momme is about 4.34 grams per square meter. That puts 19 momme at roughly 82.5 g/m² and 22 momme at roughly 95.5 g/m², a gap of about 13 g/m². So 22 momme has about 16% more silk per square meter than 19, and 19 has about 14% less than 22.

You’ll see other figures online. If a guide’s numbers don’t line up with 4.34 g/m² per momme, the math is off — and so is any comparison built on it.

How 19 and 22 Momme Differ on a Mask

Feel and weight

22 momme is the denser, more substantial fabric; 19 momme is lighter and airier. On a mask, though, you feel the whole construction, not just the silk. ZIMASILK gets much of its soft, cushioned character from its silk filling, while the Alaska Bear is a feather-light flat 19-momme mask. Two masks of the same momme can feel quite different on your face.

Light blocking

This is where most of the confusion lives. Momme describes the outer fabric only, so a 22-momme label isn’t on its own a reason to expect better blackout. Many masks have something inside: ZIMASILK uses a silk filling, and some other silk masks pair a mulberry silk outer with a polyester filling. Light that sneaks in around your nose and cheeks comes down to shape and fit — contoured cups like those on the Slip Contour, a nose pad like the one on the LitBear, and a strap that holds the mask snug without squeezing.

Durability

More silk per square meter generally means a sturdier fabric, so 22 momme has the edge on paper. But momme alone doesn’t guarantee a long life. The weave, the stitching, how you wash the mask, the detergent and how hard it gets used all count. Most masks here call for hand washing, and care is the part you control. Our silk mask care guide walks through it.

Warmth and breathability

Both weights stay highly breathable; the extra density of 22 momme doesn’t meaningfully block airflow. What makes a mask warmer is what’s inside it. A filled or padded mask runs warmer than an unfilled flat one, whatever the momme. ZIMASILK’s silk filling, for example, makes it slightly warmer than an unfilled flat mask with the same 22-momme shell weight.

Cost

22-momme masks generally cost more. In our catalog, both the premium and luxury picks are 22 momme, while 19 momme covers the entry-level end. If budget decides it, 19 momme still gets you genuine mulberry silk.

Which Momme Should You Choose?

Here’s how the choice plays out in the most common situations. For the full ranking across every type of mask, see our best silk sleep masks roundup.

Your first silk mask: 19 momme

Trying silk for the first time? 19 momme gives you the real material without a premium commitment. The Alaska Bear is the safe default: 19-momme mulberry silk on both sides, a silk-covered adjustable elastic strap, 30 colors and patterns, and hand-washable, quick-drying fabric. Skip it if you wear lash extensions — as a flat mask it presses lightly on lashes — and note the strap isn’t the widest.

Buying for two, travel or gifting: a 19-momme 2-pack

The BeeVines 2-Pack suits couples, travelers and gift-givers. You get two 19-momme mulberry silk masks, each with a soft adjustable strap, in a wide range of color pairings. They’re thinner than premium 22-momme masks — a fair trade when you want one for home and one for your bag, or one for each side of the bed. Like other flat masks, they press lightly on lashes. For more ideas, see our silk sleep mask gift guide.

Sensitive skin or elastic that digs in: 19 momme with a wide strap

LULUSILK is for anyone who hates a thin band pressing into their head. Its wide, soft headband-style strap spreads pressure instead of concentrating it, and the brand describes its mulberry silk as hypoallergenic. The trade-offs: the wider strap can muss your hair, and the flat shape gives moderate rather than total light blocking.

A hard-to-fit head: 19 momme, fully adjustable

If masks slide off or squeeze, fit is your problem, not fabric weight. The Zenssia pairs soft 19-momme mulberry silk with a fully adjustable strap the brand sells as fitting everyone from kids to adults, in a muted color palette. A snug fit also helps keep edge light out. It’s a flat mask with average blackout, so it’s not the pick for very bright bedrooms.

The 22-momme feel without the premium tier

Two masks cover this. ZIMASILK has a 22-momme, grade-6A mulberry silk shell, according to its Amazon listing, plus a silk filling for a plush, cushioned feel and an adjustable strap that fits most head sizes. The filling can shift over time and runs slightly warm. The Umisleep suits spec-focused buyers: 22-momme, grade-6A silk in a clean flat design with a soft adjustable strap. It’s a newer brand with less track record than the veterans, and colorways are limited for now.

Premium finish in a flat mask: 22 momme

Blissy is for shoppers who want the best silk grade and finish. It uses thick, dense 22-momme grade-6A mulberry silk, with excellent light blocking for a flat mask and polished finishing and packaging. The brand says its silk is hypoallergenic and OEKO-TEX certified. The catch is the strap: silk-covered elastic that isn’t adjustable, so if fit comes first, look at Zenssia or Umisleep. Blissy says the mask can be machine washed, though hand washing is gentler.

Lash extensions: shape first, momme second

Any flat mask rests on your lashes, whatever its momme. The Slip Contour uses contoured 3D eye cups that lift its 22-momme silk off your eyes for zero lash pressure and near-total blackout. It’s the clearest case of shape mattering more than silk weight. The contour does make it bulkier to pack.

Side and stomach sleepers: 22 momme with a cushioned band

The LitBear pairs 22-momme silk with a wide cushioned band, hook-and-loop adjustment and a nose pad designed to reduce light leaks, all designed by the brand for side sleepers. The styling is plain, and the hook-and-loop closure can catch on hair. Our side-sleeper guide explains why the strap matters so much in that position.

Hot sleepers: either grade, but watch the filling

Both weights breathe well, so momme isn’t the deciding factor if you run warm. Lean toward a thin, flat mask over a filled or padded one, and check the main roundup for our cooling-focused pick.

19-Momme vs 22-Momme Masks Side by Side

The table lines up the four 19-momme and five 22-momme masks in our catalog. All nine are listed as 100% mulberry silk. Momme and silk grade are as stated in each brand’s listing; a dash means the detail isn’t confirmed.

Two patterns stand out. Only one of the nine, the Slip Contour, is contoured — which is why it’s the go-to for lash extensions regardless of momme. And strap design varies far more than silk weight does, from Blissy’s fixed silk-covered elastic to Zenssia’s fully adjustable strap and LitBear’s wide hook-and-loop band. Torn between a 19- and a 22-momme mask? Strap and shape make a better tiebreaker than the three-momme gap.

How to Read a Momme Claim on an Amazon Listing

Momme is only useful when the listing is clear about what it applies to. Check these points:

• The momme applies to your color. Some sellers use different-weight fabric for different colorways of the same mask; one retailer offers 19, 22 or 30 momme depending on the color. If the momme is stated for only one version, don’t assume it covers them all.
• Both sides, or only the front? Look for mulberry silk on both sides, as the Alaska Bear and BeeVines listings state. Some masks have only a silk front shell, and the filling inside may be silk, polyester or something else.
• Grade isn’t momme. A grade such as 6A describes the quality of the silk fiber; momme describes the fabric’s weight. A 6A label alone doesn’t tell you how heavy the silk is.
• Vague wording is a red flag. No momme at all, or phrases like “satin silk” and “silk-feel,” deserve a closer look before you assume the mask is pure silk. Our silk vs. satin guide explains the difference.
• “mm” means momme. 22mm and 22 momme are the same claim.
• Higher isn’t automatically better. On a mask, 25 momme and up mainly adds weight on your face.

What About 16 Momme (or 25+)?

Below 16 momme, silk is light and semi-sheer — the weight generally used for scarves, linings and accessories. It can work for a mask you only wear occasionally, but for nightly use we’d stick to 19 or 22 momme. We don’t list any 16-momme masks.

At the other end, 25 momme and up is heavier, with a firmer hand, and mainly used for luxury bedding. That density makes sense across a pillowcase. On a small mask resting on your eyes, the extra weight is a trade-off rather than a clear upgrade — which brings the practical choice back to 19 or 22.
