ZIMASILK 22 Momme Mulberry Silk Sleep Bonnet — Black, 100% Grade 6A, Adjustable Elastic

ZIMASILK's 22 momme 100% Mulberry Silk bonnet is a breathable, hypoallergenic nightcap that protects hair from friction and moisture loss while you sleep.

This lightweight yet substantial silk bonnet is woven from Grade 6A Mulberry silk at a 22 momme weight, offering a soft, glossy surface that reduces tangles, breakage, and frizz. It’s fully lined with silk on both sides for consistent slip and comfort, and designed to fit most head sizes with an adjustable elastic band. The bonnet blends practical hair care benefits with a luxe feel, making it an easy nightly upgrade for anyone wanting gentler sleep protection for hair and scalp.

How does this silk bonnet protect hair overnight?

The smooth silk fibers reduce friction between hair and fabric, which lowers breakage and split ends compared with cotton or polyester. By minimizing rubbing, it also helps preserve hairstyles and prevents frizz, so you spend less time restyling in the morning.

• 22 momme density for durable, long-lasting silk performance
• Double-sided silk lining ensures consistent low-friction contact
• Retains hair’s natural oils to reduce dryness and static

Is the bonnet comfortable and safe for sensitive scalps?

Yes — the bonnet is made from 100% Grade 6A Mulberry silk and is OEKO-TEX certified, indicating it’s free from harmful substances often found in lower-quality fabrics. The breathable silk construction keeps the scalp cooler and gentler than many synthetic alternatives.

• Hypoallergenic silk reduces irritation for sensitive skin
• Breathable weave helps prevent overheating during sleep
• OEKO-TEX certification ensures fabric safety and purity

Will the bonnet fit my head and hair type?

The bonnet includes an adjustable elastic band designed to fit head circumferences from about 21" to 23" comfortably for most sleepers. Note that extremely full, thick, or voluminous hairstyles may not fit inside fully; fit depends on hair volume as well as head size.

• Adjustable elastic for a secure, comfortable fit
• Best suited for standard to moderate hair volume
• Free returns and a 180-day warranty if fit or quality isn’t right

How should I care for and use the silk bonnet?

To preserve the silk’s sheen and strength, hand wash gently or use a delicate machine cycle with a mild detergent and cool water, then line-dry away from direct heat. Avoid bleach and harsh chemicals; a gentle rinse before first wear can remove any natural silk scent.

• Hand wash or delicate machine wash in cool water
• Use mild detergent; avoid bleach and fabric softeners
• Air dry flat or on a line; do not tumble dry for longevity

Who this is for: The ZIMASILK 22 momme Mulberry silk bonnet is ideal for sleepers seeking an upgrade from cotton nightcaps, people with chemically treated or fragile hair, and anyone wanting to extend the life of blowouts or protective styles. It’s also a thoughtful self-care gift for friends and family who value luxury bedding accessories. If your hair is extremely thick or styled in very large updos, consider measuring your volume first; otherwise enjoy a softer, cooler, and more protective sleep routine backed by a 180-day warranty.
