A 100% Mulberry silk bonnet is the single most effective barrier between your hair and the friction of a cotton pillowcase. Without one, you accept nightly breakage, frizz, and moisture loss that undoes your daytime hair care routine. The right bonnet locks in hydration, preserves styles, and prevents split ends — all while you sleep.
I’m Mohammad — the founder and writer behind ProteinJug. This guide came from analyzing hundreds of customer reviews, comparing momme weights, double-layer constructions, and adjustable fit systems to find the bonnets that actually deliver on their promises.
Your hair deserves real silk, not satin imitations. After testing the top contenders against seven key criteria, this is the definitive resource for finding the best 100 mulberry silk bonnet for your specific hair type and sleeping style.
How To Choose The Best 100 Mulberry Silk Bonnet
Not all silk bonnets are created equal. The key differentiators lie in the construction, the silk grade, and the fit system. Here’s exactly what to check before you buy.
Momme Weight — The Density Metric
Momme (mm) measures the weight and density of silk fabric. A 22 momme silk is denser, more durable, and better at retaining moisture than a 19 momme option. For a bonnet, 22 momme offers superior longevity and smoother protection for your hair.
Layer Construction — Single vs. Double
A single-layer bonnet uses one sheet of silk, which can be sufficient for fine or short hair. Double-layer bonnets use silk on both the inside and outside, providing extra cushioning, reduced friction, and better shape retention. For long or curly hair, double-layer designs are generally more effective.
Fit and Security System
Look for either an adjustable elastic strap with a cinch or a silk tie band. Elastic straps are common and easy to use, but they can wear out over time. Tie bands offer a customizable fit but may loosen if the silk-on-silk friction isn’t strong enough. Some premium bonnets use a hybrid approach with a non-slip loop system.

In‑Depth Reviews
1. YANIBEST 22 Momme 100% Mulberry Silk Sleep Cap
The YANIBEST bonnet uses 6A grade 22 momme mulberry silk on both sides, setting a high standard for fabric quality. The all-around elastic design keeps the bonnet secure without the need for a tie, and reviewers consistently note its generous roominess — it accommodates everything from short, fine hair to thick, long 3B curls without compression.
Customer feedback highlights that this bonnet stays on throughout the night better than tie-style alternatives. The double-ply silk construction reduces friction effectively, leading to noticeably smoother hair in the morning. The included silk scrunchie is a practical bonus, extending the silk protection beyond sleep.
The main trade-off is that the adjustable strap can lose some elasticity after many washes, though most users report months of consistent performance before any change. For anyone wanting a secure, roomy, and high-quality silk bonnet, this is the easiest recommendation.
Why it’s great
- 22 momme, 6A grade silk provides maximum smoothness and durability
- Roomy interior fits long, thick, and curly hair without compression
- All-around elastic keeps the bonnet secure all night
Good to know
- Elastic may lose some tension after frequent washing
- Slightly bulkier profile than thinner bonnets
2. AWAYTR Silk Bonnet with Band
The AWAYTR bonnet is crafted from 19 momme 6A grade mulberry silk and features a reversible design with a front tie band. This model focuses on comfort for side sleepers, with a tie system that contours around the ears and temples without creating pressure points. The spacious 13.8-inch exterior offers ample room for mid-length 4a hair and voluminous blowouts.
Customer reviews consistently mention the immediate improvement over polyester or satin bonnets, with softer hair and less breakage. The reversible nature allows for a color change, and the beautiful packaging makes it a strong gift candidate. Users with fine hair particularly appreciate the reduced tangles and breakage.
Some users note that the fit can be tricky — the tie band may not cover the ears fully, and for those with very thick or long hair, the 19 momme silk feels less dense than a 22 momme alternative. If side-sleeping comfort and a fashionable look are priorities, this is an excellent choice.
Why it’s great
- Reversible design offers versatility and an elevated lounging aesthetic
- Customizable silk tie band conforms to head shape for side sleepers
- Spacious 13.8-inch interior accommodates mid-length curls
Good to know
- 19 momme silk is less dense than 22 momme options
- Fit may not cover ears for all head shapes
3. YFONG Double-Layered 100% Pure Mulberry Silk Bonnet
The YFONG bonnet is purpose-built for long hair, featuring a 27-inch length that easily accommodates waist-length tresses, thick manes, and voluminous curls. The double-layer construction uses 100% 22 momme mulberry silk on both the inner and outer layers, creating a slip surface that minimizes friction and prevents breakage.
Reviewers with dreads, long curls, and braids confirm that the elongated design allows hair to lay flat without compression, preserving styles overnight. The tie band with fixed loops provides adjustability, and the 95% polyester and 5% spandex band remains elastic without leaving forehead marks. Users report waking up to hair that requires no brushing.
Some users find the bow-style tie band cumbersome, as it can fall forward and get in the way during sleep. Additionally, the tie band itself is not silk, which some users noted. For those with hair past shoulder length, the extra space of this bonnet is a major advantage.
Why it’s great
- 27-inch length easily fits waist-length and very thick hair
- Double-layer 22 momme silk provides exceptional friction reduction
- Adjustable tie band with fixed loops stays secure
Good to know
- Bow-style tie can be cumbersome and fall forward
- Tie band is polyester/spandex, not silk
4. Kaome 100% Mulberry Silk Bonnet
The Kaome bonnet is a double-layer 22 momme silk design with an adjustable elastic strap, offering premium specs at a mid-range price point. It comes with a burn-test sample and a storage bag, verifying the authenticity of the silk. The adjustable strap allows for a customizable fit that many users find superior to non-adjustable competitors that cost twice as much.
Customer feedback emphasizes the cooling effect of real silk compared to satin, and the bonnet’s ability to stay on through a full night of tossing and turning. Users with long, thick, and curly hair report significant reductions in frizz and breakage. The beautiful packaging with clear care instructions adds to the positive unboxing experience.
A common concern is that the elastic buckle strap can slide off during the night for some users, exposing the back of the hair. The fit may also be too small for those with very thick hair. For the price, the Kaome delivers strong performance, but the strap security is something to consider if you are a restless sleeper.
Why it’s great
- 22 momme double-layer silk at a very competitive price point
- Adjustable elastic strap offers a customizable fit
- Includes burn-test sample and storage bag for authenticity confirmation
Good to know
- Elastic buckle strap may slip off for some sleepers
- May feel snug for those with very thick hair
5. RedJoe 22 Momme 100% Mulberry Silk Bonnet
The RedJoe bonnet offers a 100% mulberry silk double-layer construction at an entry-level price, making it an accessible option for those new to silk hair care. It includes a matching silk scrunchie and features an adjustable elastic strap that users rate highly for security. The reversible design allows you to change the color by turning it inside out.
Reviews highlight its effectiveness at preventing CPAP headgear hair breakage and tangles. The adjustable nature allows a good fit for smaller head circumferences, and users appreciate that it does not overheat during sleep. For many, it represents a significant upgrade from satin alternatives.
The most consistent criticism is that the bonnet runs small. Several users with shoulder-length or longer hair found it too tight, and the elastic strap can fail relatively quickly with frequent washing. This bonnet is best suited for short hair or those with smaller head circumferences.
Why it’s great
- Authentic 100% mulberry silk at a very accessible price
- Includes a matching silk scrunchie for added value
- Adjustable elastic strap provides a secure, non-slip fit
Good to know
- Runs small; not ideal for long or very thick hair
- Elastic strap may lose tension after multiple washes
6. OLESILK 100% Mulberry 22 Momme Silk Bonnet
The OLESILK bonnet uses 22 momme mulberry silk with an elegant draw cord for adjustability. The machine-washable design is a practical advantage for busy users. The soft, high-quality silk significantly reduces morning tangles and breakage, with several reviewers noting a clear improvement in hair softness and reduced overnight shedding.
For users with thin or short hair, this bonnet performs well, staying on with tighter ties and offering a comfortable fit. The fabric itself is described as beautiful and silky, and the overall construction is solid for the price range. The light silvery grey color is a popular aesthetic choice.
The bonnet’s primary limitation is its size — it is designed as a cap, not a full bonnet, and does not accommodate medium to thick hair. Users with thick or long hair report that it fails to stay on during sleep and is simply too small. It is only suitable for those with short or thin hair.
Why it’s great
- 22 momme real silk at a budget-friendly price
- Machine washable for easy maintenance
- Reduces morning tangles and breakage for thin hair
Good to know
- Too small for medium, thick, or long hair
- Draw cord may not provide a secure fit for all head shapes
7. Wonder Family 100% Mulberry Silk Bonnet
The Wonder Family bonnet focuses on a secure fit for curly hair, featuring a non-slip Wonder Loop system and a fully silk construction, including the tie band. It comes in a luxurious gift box with a storage bag, and the reversible design offers two looks in one. The 100% mulberry silk fabric reduces frizz, maintains moisture, and stays secure for restless sleepers with curl patterns.
Reviewers with curly and coily hair praise how the bonnet keeps their styles defined and frizz-free without moisture loss. The thoughtful design includes a non-slip loop that many find effective for holding the bonnet in place throughout the night. The packaging adds a premium feel that makes it suitable for gifting.
Users with straight, fine, or long hair report that the silk-on-silk tie band does not provide enough friction to stay secure, causing the bonnet to slip off. The elastic is not adjustable, which limits the fit range. This bonnet is highly effective for its target audience but is not a universal solution for all hair types.
Why it’s great
- Complete 100% silk construction, including the tie band
- Non-slip loop system works well for curly and coily hair
- Reversible design with premium gift packaging included
Good to know
- Silk tie band lacks friction for straight or fine hair
- No adjustable elastic; fit is limited to one size
