Umisleep Mulberry Silk Sleep Bonnet — 22 Momme Double-Layer Large Black+Purple, Gentle for Long Curly Hair

This silk sleeping cap pairs a 22 Momme, 6A-grade Mulberry silk inner layer with a dense satin outer shell so you get both the gentle surface of pure silk and the practical durability of satin. The bonnet’s generous 13.4" diameter and 9.8" height accommodates mid-back length hair, braids, dreadlocks, and full-volume styles. An adjustable elastic band with buckle keeps the bonnet in place without pinching, while OEKO-TEX certification confirms a level of textile safety and eco-conscious quality.

How does this bonnet protect my hair while I sleep?

The smooth silk interior reduces friction between hair and fabric, preventing breakage, frizz, and split ends while retaining natural oils and moisture. The outer satin layer adds structure and protects color-treated strands from fading and wear.

• 22 Momme 6A-grade Mulberry silk inner layer for low friction
• Outer dense satin to lock in oils and protect color
• Double-layer design limits pillow abrasion and towel-like dryness

Will it stay on all night without leaving marks?

The bonnet uses a soft elastic band with an adjustable buckle to create a secure yet gentle hold that avoids pressure points. Tuck the excess strap into the seam for a smoother fit and reduced movement while you change sleeping positions.

• Soft elastic band distributes tension evenly
• Adjustable buckle lets you fit head sizes 18"–26" comfortably
• Design prevents slipping for back, side, and stomach sleepers

Is the Umisleep bonnet large enough for thick, long, or curly hair?

Yes — with a 13.4" diameter and 9.8" height the cap leaves ample room for voluminous hair, braids, and locs without compressing styles. The roomy interior helps hairstyles retain shape, reduces the need for frequent restyling, and fits a wide range of head circumferences.

• Generous interior space for mid-back length and fuller styles
• Adaptable fit for head sizes between 18" and 26"
• Contains braids, curls, and natural volume without flattening

How does the double-layer construction improve daily use?

Combining a pure silk inner layer with a dense satin outer layer balances luxury and utility: silk protects delicate strands, while the satin exterior increases durability and reduces staining on pillowcases. It also extends time between washes and helps maintain hair color and moisture.

• Silk inner for gentleness and moisture retention
• Satin outer for abrasion resistance and color protection
• Machine-handy care when handled per silk care instructions

Who is this for? The Umisleep silk bonnet is aimed at people who want to preserve hairstyles and hair health overnight — especially those with long, curly, coily, or color-treated hair. It’s useful for anyone seeking to reduce breakage and frizz, extend time between washes, or protect treated hair. The adjustable fit and roomy interior also make it a thoughtful gift for women, teens, and anyone who uses sleepwear or loungewear routines as part of their beauty or self-care regimen.
