Simapu Mulberry Silk Sleep Cap — Steel Blue adjustable 22-momme silk-lined bonnet for curls

This lightweight night beanie pairs a 22 momme mulberry silk interior with a soft modal exterior to create a smooth, low-friction surface that preserves hairstyles and locks in natural moisture. Finished in steel blue and fitted with a half-circumference elastic strap plus an adjustable buckle, the cap accommodates head sizes from about 20.5 to 23.6 inches (52–60 cm). Designed for everyday use, it’s breathable enough for warm nights and gentle enough for sensitive scalps.

How does the silk lining protect my hair during sleep?

The 6A-grade mulberry silk lining reduces mechanical friction between hair and fabric, which helps minimize split ends, breakage and tangles. Its natural proteins and amino acids help hair retain moisture instead of absorbing it like cotton would.

• 22 momme silk interior for a smooth glide against strands
• Reduces friction that causes frizz and breakage
• Helps preserve hairstyles, curls, and braids overnight

Will this bonnet fit my head and stay comfortable all night?

The cap combines a stretchy modal outer shell with an elastic half-band and adjustable buckle so you can fine-tune the fit without tight pressure on the forehead. The design prevents marks and stays secure through sleep movements, while remaining breathable for year-round comfort.

• Adjustable strap fits head circumferences 52–60 cm (20.5–23.6 in)
• Lightweight modal exterior keeps the cap breathable
• Elastic half-circumference avoids front-line indentation

Is this bonnet suitable for different hair types and styles?

Yes — the stretch and volume-friendly shape accommodates waves, curls, short cuts, and many mid-length styles without compressing the hair. It’s especially useful for styles that benefit from less friction, such as protective styles, braids, and heat-styled hair.

• Ideal for curly, wavy, straight, braided, and dry hair
• Works for short to medium-length hair and low-volume updos
• Helps maintain style shape and reduce morning touch-ups

How else can I use this silk sleep cap beyond bedtime?

The soft, attractive bonnet doubles as a versatile accessory during skincare routines, spa days, travel, or light outdoor errands. It’s packaged in a presentable box, making it a thoughtful gift for people who value hair health and comfort.

• Useful for makeup, facial treatments, and shower protection
• Comfortable for travel, lounging, and low-impact activities
• Available in an elegant box suitable for gifting

Who is this for? The Simapu silk-lined sleep cap is aimed at anyone seeking gentler nightly hair care: people with curls or textured hair, those with short or mid-length styles, and anyone who wants to reduce friction-related damage and preserve hairstyle shape while sleeping. If you prioritize moisture retention, reduced frizz, and a customizable, comfortable fit, this steel-blue silk bonnet is a practical addition to your hair-care routine.
