ZIMASILK's 22 momme 100% mulberry silk bonnet is a breathable, hypoallergenic sleep cap designed to reduce friction, protect hair from breakage and frizz, and keep moisture locked in overnight.

Made from top-grade 6A mulberry silk on both sides, this luxury bonnet combines a glossy, gentle surface with a soft, breathable weave for comfortable nightly wear. At 22 momme the fabric feels substantial without being heavy, delivering long-lasting durability while preserving hair health and scalp comfort. The bonnet includes a premium elastic band sized to fit most heads and is OEKO-TEX certified to ensure it’s free from harmful chemicals.

How does this silk bonnet protect hair while I sleep?

The smooth silk surface reduces friction between hair and fabric, which helps prevent tangles, split ends, and overnight breakage. Silk also helps maintain hair’s natural oils and moisture, so strands feel softer and shinier in the morning. Because the material doesn’t pull on delicate fibers, it’s gentler on chemically treated or fragile hair.

• Low-friction 100% mulberry silk minimizes tangling and breakage.
• 22 momme weight balances durability with airflow.
• Retains natural oils to reduce dryness and frizz.
• Double-sided silk finish for consistent protection inside and out.

Will the bonnet stay on all night without feeling tight?

The bonnet is built with a premium elastic stay-on band that conforms to 21"–23" head sizes, helping it remain secure through typical sleep movements. The elastic is designed to be flexible rather than constrictive, offering a snug fit without causing headaches. Note that fit can change depending on hair volume—very full hairstyles may require a larger cap.

• Adjustable elastic band holds the bonnet in place during sleep.
• Snug yet gentle fit for most adult head sizes (21"–23").
• Not ideal for extreme thick or high-volume hair styles.
• Lightweight construction avoids pressure points on the head.

Is the silk safe for sensitive skin and treated hair?

This bonnet uses Grade 6A mulberry silk and carries OEKO-TEX safety assurance, meaning it’s free from many common harmful substances. Silk’s hypoallergenic properties are well-suited to sensitive scalps and reduce irritation compared with coarse fabrics. Because it’s smooth and breathable, it’s also a gentle option for color-treated, chemically processed, or heat-styled hair.

• OEKO-TEX certified; free from harsh manufacturing residues.
• Hypoallergenic silk reduces scalp irritation risks.
• Safe for use with color-treated or fragile hair types.
• Breathable weave helps regulate temperature at night.

How do I care for this silk bonnet to keep it lasting?

To preserve the silk’s sheen and elasticity, wash on a gentle cycle with a mild detergent or hand-wash in cool water. Avoid bleach, high heat, or rough agitation; line-dry flat out of direct sunlight. With proper care, the 22 momme silk maintains its smooth surface and resilience through many uses.

• Hand wash or use gentle machine cycle with cold water.
• Use mild detergent formulated for delicate fabrics.
• Air-dry flat, away from direct sunlight and heat sources.
• Avoid bleach and fabric softeners to protect fibers and elasticity.

Who is this silk bonnet best for? If you want a higher-weight, high-quality silk sleep cap that prioritizes hair protection, moisture retention, and a chemical-safe construction, this ZIMASILK 22 momme bonnet is a strong choice. It suits people with fine to medium hair, those with chemically treated or fragile strands, and anyone seeking a breathable, hypoallergenic nightcap.
