YFONG Mulberry Silk Sleep Bonnet — 22mm 6A Lined Double-Layer Black with Adjustable Non‑Slip Band

YFONG's Real Mulberry Silk Double-Layer Bonnet is a breathable, cushioned sleep cap with a 6A 22-momme silk inner layer and an adjustable non-slip band to protect hair overnight.

If you want to reduce frizz, retain moisture, and wake up with smoother, more manageable hair, this bonnet pairs a certified mulberry silk interior with a durable satin exterior and a wide adjustable elastic for secure all-night wear. Designed to fit most head sizes and large hair volumes, it works for curls, braids, long hair, weaves and protective styles without flattening or causing breakage.

How does the silk lining benefit my hair while I sleep?

The inner lining is genuine 6A-grade mulberry silk (22 momme), OEKO-TEX Standard 100 certified for purity. Silk's smooth surface reduces friction against strands, helping limit tangles, split ends and mechanical damage compared with cotton pillowcases.

• Preserves natural oils and moisture to reduce dryness.
• Minimizes friction to prevent breakage and frizz.
• Contains amino acids naturally present in silk that help maintain hair softness.

Will this bonnet stay on throughout the night?

The bonnet uses a wider elastic band made from soft polyester fiber plus an adjustable buckle, letting you tighten or loosen the fit. The combination of a roomy inner cap and the configurable band keeps the bonnet secure for back, side, or stomach sleepers without uncomfortable pressure.

• Adjustable circumference from 22" to 27.5" to match most head sizes.
• Wide non-slip band reduces sliding and rolling off during sleep.
• Soft band material avoids leaving marks or pulling hair at the hairline.

Is the bonnet large enough for thick or curly hair and protective styles?

Yes—the bonnet measures about 13.4 inches in diameter and is intentionally spacious to accommodate voluminous curls, long lengths, braids, and buns. The double-layer construction adds gentle structure so bulkier hairstyles sit comfortably inside without being flattened.

• Roomy interior for natural, coily, and textured hair types.
• Works over braids, weaves, extensions, and rollers without deformation.
• Outer satin layer helps prevent dye or product transfer to pillowcases.

How durable is the bonnet and will it keep its shape and color?

The bonnet features a double-layer build: a pure silk inner layer for hair contact and a colorfast satin outer shell for resilience and easy care. This pairing protects the delicate silk while providing outer durability for repeated use and gentle washing.

• Outer satin resists fading and shields pillows from oils or styling products.
• Inner 22-momme silk retains its smooth texture over time when washed gently.
• Sturdy stitching and adjustable hardware extend the bonnet's lifespan.

Who is this for? This YFONG double-layer silk bonnet suits anyone wanting to preserve hair health overnight: people with curly, natural, or long hair; those who wear protective styles like braids or weaves; and anyone seeking a comfortable, adjustable sleep cap that reduces morning styling time. It's also packaged as a gift-ready option for special occasions when you want a practical, high-quality hair-care present.
