YFONG Mulberry Silk Sleep Bonnet Large — Double-Layer, 22 Momme Lining & Adjustable Non-Slip Band

The YFONG Mulberry Silk Lining Bonnet is a double-layer, adjustable sleep cap that protects hair overnight using a 22 Momme 6A mulberry silk inner lining and a non-slip widened elastic band.

Designed to reduce friction, retain moisture, and minimize breakage, this bonnet pairs a pure mulberry silk interior with a durable satin exterior and an upgraded adjustable buckle for a secure fit. With a 13.4-inch interior diameter and an adjustable head circumference from 22 to 27.5 inches, the cap adapts to a wide range of hair volumes and styles—curly, coiled, long, braided, or styled with rollers. OEKO-TEX certified silk ensures a breathable, skin-friendly surface while the colorfast outer satin preserves oils and resists pillowcase stains.

How does this bonnet protect my hair while I sleep?

The smooth silk lining lowers surface friction so strands glide rather than rub, which helps reduce tangles, frizz, and split ends. Silk's natural amino acids also support moisture retention and gentle hair handling overnight without abrasive fibers.

• 22 Momme 6A mulberry silk lining for low-friction sleep contact
• Double-layer construction reduces abrasion and increases durability
• Helps keep natural oils and product moisture close to the hair shaft

Will the bonnet stay on all night or slip off?

This bonnet uses a wider elastic band made from polyester fiber plus an adjustable buckle to hold a consistent, comfortable fit through movement. The band is designed to distribute pressure evenly, reducing the chance of the cap rolling or sliding regardless of sleep position.

• Wider elastic band for improved grip and comfort
• Adjustable buckle lets you set the head circumference precisely
• Soft, elastic finish minimizes marks or pressure around the hairline

Is the size suitable for thick or very long hairstyles?

Yes—the interior diameter and adjustable range accommodate high-volume styles, braids, and updos without flattening or compressing hair. The roomy 13.4-inch dome and extendable circumference provide space for curls, weaves, and protective styles while ensuring the silk lining remains in contact with your hair.

• 13.4-inch interior diameter for generous hair room
• Adjustable head circumference from 22 to 27.5 inches
• Works with braids, buns, rollers, and long or curly hair

How should I care for the bonnet to keep silk soft and long-lasting?

Gentle cleaning and air-drying preserve the silk’s natural properties and the bonnet’s shape. Avoid high-heat washing or tumble drying; opt for hand wash or a delicate machine cycle in a mesh laundry bag using mild detergent formulated for silk.

• Hand wash or delicate machine cycle in cold water
• Use mild silk-friendly detergent; avoid bleach and strong detergents
• Air dry flat or hang away from direct sunlight to maintain shape
