ZIMASILK Mulberry Silk Bonnet for Sleeping — Black, 100% 6A Double-Layer with Roomy Fit

ZIMASILK's 100% Mulberry Silk Bonnet is a double-layered sleep cap designed to protect long hair overnight while offering a breathable, secure fit with cooling long ties.

This black silk bonnet combines high-grade 6A Mulberry silk with a thoughtful double-layer construction to reduce friction, preserve hairstyles and enhance nighttime comfort. OEKO-TEX certification and hypoallergenic materials make it suitable for sensitive skin. The bonnet’s long, ice-silk style ties give a pressure-free hold, and the roomy design accommodates long or voluminous hair without flattening curls.

How does this bonnet protect hair while I sleep?

The smooth surface of 100% Mulberry silk reduces rubbing between hair and fabric, which helps minimize breakage and frizz. The double-layer construction adds durability and a softer internal surface that cushions hair, especially along ends and roots. Because silk naturally repels moisture, it helps retain the hair’s natural oils compared with cotton alternatives.

• 100% 6A-grade Mulberry silk reduces friction and split ends
• Double-layer build for extra softness and long-lasting shape
• Silk’s low absorbency helps preserve hair moisture and treatments

Will it stay on all night without feeling tight?

The bonnet uses long cooling ice-silk ties designed for a pressure-free wrap around the head. You can tie looser or tighter depending on sleep position, and the roomy cap holds long hair without compressing styles. The breathable silk keeps overnight heat lower than many synthetic caps.

• Long, soft ties provide adjustable, secure fit without tight bands
• Roomy interior fits long and thick hair without flattening
• Breathable silk minimizes overnight heat build-up

Is this bonnet appropriate for sensitive skin or scalp?

Yes — ZIMASILK’s bonnet is OEKO-TEX certified and made from hypoallergenic Mulberry silk that is gentle on skin and scalp. The fabric resists common irritants and is suitable for those who react to rougher textiles. Care instructions recommend hand washing in cold water with mild detergent to preserve the silk and maintain its skin-friendly properties.

• OEKO-TEX certified silk for reduced chemical exposure
• Hypoallergenic fabric reduces likelihood of irritation
• Simple hand-wash care keeps fibers soft and safe for sensitive skin

How else can I use the bonnet besides sleeping?

The versatile silhouette works as a treatment cap, hair wrap during moisturizing or protein treatments, and a protective cover during beauty routines. Its elegant black finish and neat ties make it suitable for travel, salon visits, or lounging at home. Packaged gift-ready, it also serves as a practical present for anyone who values hair care.

• Use as a treatment cap for deep conditioning or overnight masks
• Elegant black design fits travel and at-home beauty routines
• Comes boxed and gift-ready with 180-day customer support
