Your skin and hair avoid nightly friction with a 100% Mulberry silk sleep mask, unlike cheap polyester or satin blends that tug at your delicate eye area and hairline.

How To Choose The Best 100% Mulberry Silk Sleep Mask
Not every mask labeled “silk” delivers the same experience. The biggest trap is a product that uses silk only on the outer layer and fills the inside with polyester or satin. You need a mask that is 100% Mulberry silk on both sides and inside, with a momme weight that actually feels substantial against your skin.
Momme Weight — The Density That Matters
Momme (abbreviated as “mm”) measures the weight of the silk fabric. A higher number means denser, more durable, and more opaque silk. Most quality masks sit at 22 momme. Some premium options go up to 25 momme, which provides a noticeably thicker feel and better light blocking without adding bulk. Anything below 19 momme tends to feel thin and may let light through.
Flat vs. Contoured Design
Flat masks press directly against your eyelids and lashes, which can cause discomfort if you have long lashes or lash extensions. Contoured masks have molded eye cups that create space around your eyes, letting you blink freely and preventing pressure on your lashes. The depth of these cups matters — most are 10-12mm deep, while some reach 14mm for extra clearance.
Strap Quality and Adjustment
A non-adjustable strap is a dealbreaker for many sleepers. If the band is slightly too loose or too tight, the mask shifts during the night, letting light in or waking you up. Look for an adjustable strap wrapped in silk so it doesn’t snag your hair. Some masks use a buckle system, others use Velcro — both work, but the silk covering is what prevents tangles.

In‑Depth Reviews
1. Fishers Finery 25 Momme Pure Mulberry Silk Sleep Eye Mask
The densest silk you can put on your face at 25 momme, beating the standard by a significant margin.
This mask uses 25 momme Mulberry silk, while most competitors use 22 momme. Thicker silk means richer texture and better opacity — you get a deeper blackout without needing a padded lining. The exterior, interior, and stuffing are all 100% silk, so there is no hidden polyester touching your skin. Buyers report it is “ultra-soft, thick, no eye pressure” and that the “two-prong strap stays in place” all night.
Unlike the LitBear contoured mask, the Fishers Finery is a flat design with dual anchor points on the strap, which helps distribute pressure evenly rather than pulling on one spot. One caveat buyers mention: “can slip off during sleep” if you move a lot, because the flat shape has less grip than a contoured cup. The mask also comes in undyed white, which some buyers found “not as dark” as the black version. It is OEKO-TEX Standard 100 certified, meaning it has been tested for over 1,000 harmful substances.
At 3.88 ounces, it is noticeably heavier than the 1.41-ounce SECZIPE below, but that weight comes from denser silk rather than padding. For anyone who wants the absolute thickest Mulberry silk available in a sleep mask, this is the one.
Why it leads
- 25 Momme silk
- 100% Mulberry silk on both sides and inside filling
- Adjustable strap with dual anchor points reduces pressure
What to know
- Flat design may shift on active side sleepers
- Undyed white variant lets in more light than black
- Requires hand wash or dry clean
Ideal for: Any sleeper who prioritizes fabric density and wants the most substantial silk feel against their skin.
Consider alternatives if: You are a restless side sleeper who needs a contoured cup to keep the mask in place overnight.
2. MATASSE 100% Mulberry Silk Sleep Mask 22 Momme Grade 6A
Industry-leading 14mm eye cavities mean zero pressure on lashes, even with extensions.
The MATASSE mask stands apart with 14mm deep contoured eye cups. This extra room allows you to blink naturally, keep your eyes open under the mask, and never smudge makeup or lash extensions. The 22 momme Grade 6A long-fiber Mulberry silk on both sides is OEKO-TEX Standard 100 certified, so no harmful chemicals touch your face. The adjustable silk-covered strap spans 18 to 26 inches and avoids snagging hair.
Buyers confirm it “completely blocks out light and is comfortable” and that it “stays in place through the night” even for side sleepers. One reviewer noted the mask is “a little slippery” and requires “extra tightening” to prevent shifting, but still rated it 4 out of 5 stars. The contoured nose bridge and curved side panels work together to block light from all angles, giving you total blackout. At just 1.06 ounces, it is lighter than the 7.04-ounce Slip Contour mask, making it less likely to feel heavy on your face.
For people with long lashes or extensions who have struggled with flat masks pressing against their eyes, this contoured design solves that problem without adding bulk. The trade-off is that the silicone-like coating on the outside silk can slide on certain pillowcases.
Standout features
- 14mm deep eye cups
- OEKO-TEX Standard 100 certified material
- Adjustable silk-covered strap fits most head sizes
Points to note
- Outer silk can be slippery, causing slight movement on smooth pillowcases
- Contoured shape may not suit those who prefer a flat, low-profile mask
Best suited for: Anyone with long lashes, lash extensions, or sensitive eyes who needs room to blink freely under the mask.
Look elsewhere if: You prefer a completely flat mask that disappears under your face — contoured cups have a noticeable presence.
3. TheSleepGuard Pure Silk Sleep Mask [100% 6A Mulberry Silk, 22 Momme]
Luxury unboxing experience with Oeko-Tex certified 22 momme silk that feels premium from the start.
TheSleepGuard puts effort into packaging that “has the WOW factor,” making this a strong gifting candidate. The mask itself is 100% 6A Mulberry silk at 22 momme, Oeko-Tex certified so you know exactly what chemicals are absent. Buyers describe it as “very comfortable, cool, lightweight” and say it “blocks light well” and “feels amazing” against the skin.
The critical trade-off: the strap is not adjustable. Multiple owners mention “the only issue is that it isn’t adjustable, so it feels a little loose on me” and “the strap was too loose for me and kept slipping off while I slept.” At 5.29 ounces, it is the heaviest mask here. That weight comes from dense silk fabric, not padding, but combined with the fixed strap, it may shift on smaller heads. The mask is flat (not contoured), so if you have long lashes, you may feel them brush against the silk.
If you have an average or larger head size and want a solid silk mask with impressive packaging, this works well. For anyone with a smaller head who needs a snug fit, the non-adjustable strap is a real limitation.
What shines
- Oeko-Tex certified 6A Mulberry silk at 22 momme
- Premium gift packaging with high-end unboxing
- Cool, lightweight fabric feel despite weight
Watch for
- Strap has no adjustment — may be loose on smaller heads
- At 5.29 oz it is the heaviest mask reviewed
- Flat design presses on lashes
Reach for it if: You have an average-to-large head and want a gift-ready silk mask with certified material quality.
Think twice if: You have a smaller head circumference or prefer a contoured design that avoids lash contact.
4. SUNDAYSILKS Exclusive Mulberry Silk Sleep Mask
Five-time winner among buyers who tried multiple masks before landing on this one.
The SUNDAYSILKS mask uses premium Mulberry silk fibers and a Velcro adjustable strap that does not snag hair — a common complaint with hook-and-loop closures. Customers note it is “super soft and comfortable,” “blocks all light,” and one buyer stated “I tried 5 before this one.” The mask weighs 7.05 ounces, making it one of the heavier options, but that weight is distributed evenly across a flat design that covers the full eye area without nose gaps.
The cooling breathability of the silk is a consistent theme. Several buyers mention it “doesn’t overheat your face” and provides “natural ventilation,” which matters if you run warm at night. The Velcro strap allows micro-adjustments that a buckle system cannot match — you can tighten it exactly to your head size. One buyer mentioned it helps with “migraine light sensitivity” and that “it doesn’t cause pilling or unsewing” after extended use. Unlike the flat TheSleepGuard, this mask has a slightly wider cut that covers more of the forehead and temple area.
The main hesitation is the price point in the mid-range tier. Reviewers point out it is “pricey but a very good mask,” with one calling it “high-end luxury without the price tag.” If you have tried cheaper masks and found them lacking in coverage or durability, this is worth the step up.
Strengths
- Adjustable Velcro strap with hair-friendly design
- Excellent light blocking with no nose gap reported
- Breathable silk stays cool through the night
Weaknesses
- Heavier than average at 7.05 oz
- Flat design may not suit lash extension wearers
Best for: Side sleepers and migraine sufferers who need a breathable, fully adjustable mask that blocks all light without pressure points.
Pass if: You want the lightest possible mask or need deep eye cups for lash clearance.
5. Slip Contour Sleep Mask | 100% Pure Mulberry Silk
The brand that sets the standard for silk sleepwear, trusted by lash extension wearers for years.
The Slip Contour mask uses 22 momme Mulberry silk and a shaped eye cavity that keeps fabric away from your lashes entirely. Buyers with “super long lashes” confirm they never touch the mask. At 7.04 ounces, it is similar in weight to the SUNDAYSILKS option, but the contoured shape creates a tent over your eyes rather than lying flat. The adjustable strap helps dial in the fit, though one side sleeper noted “there is a little gapping that lets some light in due to the shape.”
The brand reputation matters here — one buyer has owned their Slip mask for “over 5 years” and bought a second for replacement, calling it “the best sleep mask money can buy.” That longevity speaks to the material quality and construction. Unlike the MATASSE contoured mask which uses a buckle strap, the Slip uses a broader adjustable band that some find more comfortable. The hypoallergenic silk is naturally breathable and temperature-regulating, so it does not trap heat like synthetic alternatives.
It is the most expensive mask in this roundup. For that price you get a proven design that holds up for years, but if you only need a mask for occasional travel, the LitBear or SECZIPE will serve you just fine at a fraction of the cost. Several buyers who tried multiple masks before settling on Slip confirm it is “worth the price.”
Why it stands out
- Proven durability — shoppers say 5+ years of use
- Contoured design eliminates lash contact completely
- Breathable, hypoallergenic Mulberry silk
What holds it back
- Highest price in the roundup
- Contour shape can gap at the nose for some face shapes
Choose this for: Long-term daily use where comfort, lash protection, and brand trust matter more than upfront cost.
skip it if: You have a modest budget or want a mask that conforms completely flat against your facial contours.
6. LitBear 100% 22 Momme Mulberry Silk Sleep Mask – 3D Contoured
Contoured eye cups and an adjustable strap at an entry-level price point that punches above its weight.
The LitBear mask delivers 22 momme Mulberry silk in a contoured shape with a generous 21-26 inch adjustable strap, making it one of the few value-tier masks to offer both eye cup clearance and fit customization. Buyers report it is “comfortable, blocks light well, cushioned so eyes can open without rubbing” and that the “nose space for breathing” is well-designed. The mask comes with a compact travel pouch that fits easily into a bag.
At 2.4 ounces, it is lighter than the TheSleepGuard mask at 5.29 ounces., so it feels almost weightless on your face. However, some owners mention the silk strap can be “too slippery” and that the strap is “sewn at wrong angle, doesn’t sit properly.” For side sleepers with wider faces, one reviewer found the mask “shifts, presses eye” because the eye cups may not align perfectly with wider-set eyes. The mask is best suited for back sleepers or those with narrow-to-average face widths.
Given the contoured design and 22 momme silk at a budget-friendly price, this is a compelling entry point if you want to try a 3D mask without committing to a premium investment. Just be aware that the fit is not universal — it works best on smaller and narrower faces.
What you get
- 22 Momme Mulberry silk with contoured eye cups
- Adjustable strap from 21 to 26 inches
- Lightweight at 2.4 oz with travel pouch included
Trade-offs
- Slippery strap may not hold position for some users
- Eye cup spacing best suited for narrow-to-average faces
Best for: Budget-conscious buyers with smaller face shapes who want contoured eye cups and pure silk without the premium price tag.
Reconsider if: You have a wide face or are a restless side sleeper who needs the mask to stay locked in place all night.
7. SECZIPE 100% Mulberry Silk Sleep Mask with Adjustable Band
Generously sized for full face coverage while still being the lightest mask in the lineup.
The SECZIPE mask comes in a large size that covers more of your forehead, temples, and cheeks than standard masks, making it an option for those who find typical sleep masks too small.
The adjustable band helps you find the right tension, though some customers note it is “a little bulky” and can “slide around a little” if you wear it on the looser side to avoid headaches. The flat design (not contoured) means it presses against your lashes, so it is not ideal for lash extension wearers. Light blocking is rated 9/10 by buyers, with the large cut effectively sealing out ambient light from all angles. It is machine washable, which adds convenience over the hand-wash-only alternatives.
For the price point, this delivers genuine Mulberry silk in a generous cut that suits wider faces or anyone who wants their entire eye area covered. The trade-off is the flat shape that contacts lashes directly and the slightly bulky feel some buyers mentioned.
Highlights
- Large cut covers full eye area for wider faces
- Weighs only 1.41 oz — lightest mask reviewed
- Machine washable for easy care
Limitations
- Flat design presses on eyelashes
- Can feel bulky on the bridge of the nose
Ideal for: Those with wider faces or larger head sizes who need full coverage and prefer an ultralight, machine-washable mask.
Not for: Lash extension wearers or anyone who wants a contoured shape that keeps fabric off their eyelids.
Understanding the Specs
Momme Weight: Why 22 vs 25 Matters
Momme (abbreviated “mm”) measures the density of silk fabric. A 25 momme mask has more silk weight per square inch than a 22 momme mask. This translates to a thicker, more opaque fabric that blocks light better and feels more substantial against your skin. Most premium masks use 22 momme for a good balance of softness and durability, while 25 momme is considered luxury-tier. Masks below 19 momme are often too thin to block light effectively and may degrade faster.
Contoured vs Flat Design
A flat mask sits flush against your face, pressing against eyelids and lashes. A contoured mask uses molded eye cups that create space around your eyes, typically 10-14mm deep. Contoured designs let you blink freely, protect lash extensions, and reduce pressure on the eye area. The trade-off is that contoured masks can shift more on side sleepers and may leave small gaps at the nose bridge if the shape does not match your face well. Flat masks tend to stay more secure but apply direct contact to your lashes.

For most people, the best 100% mulberry silk sleep mask overall is the Fishers Finery 25 Momme because its denser silk provides class-leading fabric quality and total light blocking with an adjustable, dual-anchor strap. If you want deep contoured eye cups for lash protection, grab the MATASSE with 14mm eye cups. And for the best value that still delivers 22 momme silk and contoured design, the standout is the LitBear 3D Contoured mask.
