Umisleep Mulberry Silk Sleep Bonnet — Double-Sided 22 Momme, Jet Black, Roomy Non-Slip Fit for Long Curly Hair

Umisleep’s double-sided 22 momme 100% real mulberry silk bonnet is a roomy, non-slip sleep cap designed to protect long, curly, or fragile hair overnight while keeping styles intact.

This silk sleep bonnet combines two layers of premium 6A-grade mulberry silk, an expanded soft elastic band with an adjustable buckle, and a generous interior to cradle long or voluminous hair. Certified OEKO-TEX STANDARD 100, the bonnet prioritizes gentle fabric against skin and strands, helping to reduce friction and preserve moisture compared with cotton alternatives. The jet-black color option is versatile and flattering for nightwear or at-home beauty routines.

How does this bonnet protect my hair while I sleep?

The double-sided 22 momme silk creates a smooth barrier between hair and rough surfaces, reducing rubbing and the resulting breakage and frizz. Because silk is less absorbent than cotton, it helps preserve natural oils and leave hair feeling softer in the morning.

• 22 momme 100% 6A-grade mulberry silk on both inner and outer layers
• Low-friction surface to minimize breakage and split ends
• Helps maintain moisture and reduce morning frizz

Will the bonnet stay on through the night?

Yes — the bonnet features a wider, soft elastic band built into the rim plus an adjustable buckle, so you can fine-tune the fit for secure, comfortable wear. The design accommodates different sleeping positions without pinching or sliding.

• Wide polyester-fiber elastic for a snug but gentle hold
• Adjustable buckle lets you position the band to your comfort
• Engineered to remain in place whether you sleep on your side, back, or stomach

Is this bonnet big enough for thick, long, or braided hair?

Yes — with a roomy 13.4" diameter and 9.8" height, this bonnet suits head circumferences from about 18" to 26" and accommodates mid-back-length and longer hair, including braids and voluminous curls. The extra interior space helps maintain hair shape without compressing styles.

• 13.4-inch internal diameter gives ample volume room
• 9.8-inch height fits long ponytails, buns, and braids comfortably
• Adjustable fit accommodates a wide range of head sizes

How durable and versatile is the silk construction?

The double-layer construction adds durability compared with single-layer silk while preserving a soft hand and breathable feel. The bonnet is suitable for nightly sleep, as well as routines like makeup, skincare, or home chores when you want hair out of the way without creasing.

• Double-layer silk improves longevity and maintains softness
• OEKO-TEX STANDARD 100 certification for safer materials
• Stylish enough for at-home wear and thoughtful as a gift
