ZIMASILK 100% Mulberry Silk Sleep Bonnet for Long Hair — Navy Blue, Double-Layer with Tie Band

ZIMASILK's 100% Mulberry Silk Bonnet is a double-layer, tie-band sleep cap designed to protect long hair overnight while staying comfortably in place.

This navy-blue silk bonnet combines 6A grade Mulberry silk, a two-layer construction and long cooling ties to reduce friction, control frizz and keep hairstyles intact from bedtime through morning. Built with OEKO-TEX certified fabric and a hypoallergenic makeup, the cap aims to be both gentle on hair and skin and durable enough for nightly use. It arrives gift-boxed and backed by ZIMASILK's customer support to give buyers a premium experience right out of the box.

How does this bonnet protect long or textured hair overnight?

The silky surface reduces rubbing between hair and pillow, which helps prevent split ends, frizz and tangles. The double-layer design adds softness and a gentle barrier that preserves moisture and minimizes breakage, making it especially useful for longer or finer strands.

• 100% 6A-grade Mulberry silk interior for low friction
• Double-layer construction for extra protection and longevity
• Generous interior space to accommodate long, thick or textured hair
• Tie band secures bonnet without tight elastic pressure

Will the bonnet stay on through the night without slipping?

Yes — the long, ice-silk ties let you adjust and secure the wrap so it stays put without pinching or cutting circulation. The design avoids tight elastic bands that can leave marks or pull at roots, giving a pressure-free fit that remains comfortable for all-night wear.

• Cooling long tie bands for customized fit and stable hold
• No tightened elastic at the head to prevent pressure points
• Wrap-style fit adapts to different head sizes and hair volumes

Is the material safe for sensitive skin and easy to care for?

The bonnet uses OEKO-TEX certified silk and is described as hypoallergenic, making it a sensible option for those with sensitive skin or scalps. Care is simple: hand wash gently in cold water with mild detergent and avoid bleach to preserve the silk's sheen and strength.

• OEKO-TEX certified silk — tested for harmful substances
• Hypoallergenic fabric suited to sensitive skin types
• Hand wash cold and air dry recommended to maintain quality

How can this bonnet fit into a hair-care or beauty routine?

The ZIMASILK bonnet works as an overnight protector, a treatment cap for conditioning sessions, or a travel-friendly option to maintain styles between washes. Its elegant navy finish and boxed presentation also make it a convenient gift for beauty-conscious friends and family.

• Use nightly to extend blowout or styled looks
• Wear during deep-conditioning treatments to lock in product
• Compact enough for travel or keeping in a handbag for touch-ups

Who is this for: The ZIMASILK 100% Mulberry Silk Bonnet is made for anyone wanting a gentler overnight option for long, fine, curly or chemically treated hair — especially people who prefer a pressure-free tie closure and OEKO-TEX certified materials.
