Simapu Silk Sleep Cap Bonnet for Women — Black, 22 Momme Mulberry Silk Lined & Adjustable

Simapu's 100% Mulberry Silk Lined Sleep Cap is a breathable, adjustable silk bonnet designed to protect curls and seal in moisture while you sleep.

This lightweight night beanie pairs a 22 momme pure mulberry silk interior with a soft modal outer layer to reduce friction, minimize frizz, and preserve hairstyles overnight. The cap includes an elastic half‑circumference band and an adjustable buckle so it fits most adult head sizes comfortably without leaving front-line marks. It’s made for everyday wear, from sleeping to skincare routines, and is presented in an elegant gift box.

How does this silk bonnet reduce frizz and breakage?

The premium 6A mulberry silk lining provides a smooth surface that allows hair to glide rather than catch against fabric. Silk's natural structure helps decrease friction compared with cotton or synthetic materials, which reduces tangles and split ends over time.

• 22 momme mulberry silk interior for lower friction
• 18 amino-acid-rich silk fibers that help preserve hair moisture
• Gentle modal outer shell to protect the silk layer and add softness

Will the cap stay on for different hair types and head sizes?

The design combines a half-circumference elastic band with an adjustable buckle to secure the bonnet without pinching the forehead. Its stretch accommodates a range of hairstyles—short to mid-length, waves, curls, braids and relaxed hair—while fitting heads from 20.5 to 23.6 inches (52–60 cm).

• Elastic strap for a flexible, comfortable hold
• Adjustable buckle for personalized tension and fit
• Lightweight breathability keeps you cool year-round

How should I use and care for this silk sleep cap?

Use the bonnet nightly to protect styles and reduce morning frizz, or keep it on during skincare and makeup routines to prevent product transfer to hair. Hand wash or machine wash on a delicate/silk cycle with mild detergent, then air dry flat to maintain the silk’s texture and the modal’s shape.

• Wear while sleeping, doing skincare, or light activities
• Cold hand wash or delicate machine cycle with silk-safe detergent
• Air dry to preserve silk sheen and elastic integrity

What makes this bonnet a good gift or travel companion?

The slim, flexible construction packs flat and resists wrinkles, making it ideal for vacations, overnight stays, or gym bags. The elegant gift box adds presentation value for birthdays, holidays, or as a thoughtful self-care present for friends and family.

• Compact, packable design for travel and storage
• Presented in an attractive gift box
• Versatile use for spa days, sleeping, makeup, or lounging

Who is this for? The Simapu 100% Mulberry Silk Lined Sleep Cap suits anyone wanting to protect their hair during rest or daily routines—especially those with curls, waves, braids, or chemically treated hair who want to minimize friction and maintain moisture.
