Simapu 100% Mulberry Silk-Lined Sleep Cap — Purple Adjustable Bonnet with 22-momme Silk for Frizz Control

This Simapu sleep cap is a breathable, adjustable bonnet lined with 100% 22-momme mulberry silk to protect hair from friction, frizz, and moisture loss while you sleep.

Lightweight and thoughtfully constructed, the Simapu silk-lined night cap pairs a pure mulberry silk interior with a soft modal exterior to create a gentle, low-friction barrier between your hair and regular fabrics. Designed for everyday use, the bonnet combines an elastic half-circumference band and an adjustable buckle so it fits most adult head sizes without tight pressure, making it a practical choice for preserving curls, waves, braids, and short-to-mid length styles.

How does this cap reduce breakage and frizz?

The silk lining provides a smooth surface that minimizes friction, which reduces tangling, split ends, and surface damage. Mulberry silk is naturally lower friction than cotton or synthetics, helping hair retain its natural oils and shine overnight.

• 22-momme 100% mulberry silk interior for a satin-smooth sleep surface
• Silk contains amino acids that help maintain hair moisture balance
• Modal outer layer adds softness and a skin-friendly touch

Will this bonnet fit my head and stay comfortable through the night?

The Simapu sleep cap uses a lightweight elastic band paired with an adjustable buckle so you can fine-tune the fit without creating pressure marks on the forehead. Its slightly slouchy beanie profile accommodates varying hair volumes while staying breathable for year-round wear.

• Adjustable strap fits head circumferences about 20.5–23.6 inches (52–60 cm)
• Half-circumference elastic prevents slipping while avoiding tightness
• Breathable construction keeps the scalp cool in warmer seasons

Is this bonnet suitable for my hair type and routine?

The silk-lined design works well for curls, waves, straight hair, braids, and chemically treated or dry hair by reducing friction and locking in moisture. It’s lightweight enough for nightly use and versatile enough to wear during skincare, makeup, or spa routines.

• Ideal for short to mid-length hairstyles and moderate hair volumes
• Helps maintain styled looks, such as curls and braids, overnight
• Suitable for use during sleep, showers, or beauty routines

How should I care for the silk sleep cap to keep it lasting?

Gentle cleaning preserves both the silk lining and the modal exterior. Follow mild washing methods and avoid heat to keep the silk smooth and resilient over time.

• Hand wash or use a delicate cycle with cold water and mild detergent
• Air dry flat; avoid tumble drying and direct high heat
• Store in a dry place or the included gift box to prevent crushing

Who is this for: The Simapu 100% Mulberry Silk Lined Sleep Cap is designed for anyone who wants an easy, non-invasive way to protect hairstyles and reduce overnight damage—particularly those with curly, wavy, or chemically treated hair, and people who value breathable, adjustable headwear for nightly care or multi-use routines. Packaged attractively, it also serves as a convenient gift for friends or family who care about hair health and comfortable sleep accessories.
