YFONG 22 Momme Double-Layer Mulberry Silk Bonnet for Long Hair — Black, Roomy Sleep Cap with Adjustable Tie

YFONG's double-layer 22 momme mulberry silk bonnet is a roomy sleep cap built to protect long, thick, or curly hair overnight while staying comfortably secure.

This bonnet pairs two full layers of 6A 22-momme mulberry silk—inside and out—to reduce friction, lock in moisture, and give fragile styles gentle, low-friction coverage. Its elongated cut accommodates long or voluminous hair without squashing curls or flattening blowouts, while the adjustable elastic tie and fixed loops let you customize fit and keep the cap in place through movement.

How does the double-layer silk protect my hair while I sleep?

The two silk layers create a smooth, slip surface that minimizes tugging and rubbing between hair fibers and fabric. That reduced friction helps limit breakage, frizz, and split ends compared with cotton or single-layer caps. Silk’s natural structure also helps retain hair’s moisture level rather than absorbing it from strands.

• Inner and outer 100% 22-momme mulberry silk for full slip and shine preservation
• Less friction equals fewer broken strands and reduced frizz
• Silk helps maintain hair’s natural oils and moisture balance

Will this bonnet fit long or thick hair without flattening styles?

The bonnet’s long 68 cm (26.77 in) design gives generous internal volume so hair can lie naturally without being compressed. That roomy shape is ideal for waist-length hair, braids, large curls, and voluminous blowouts that need space to keep their shape. The relaxed interior prevents knots that form when hair is cramped into small caps.

• Extended length accommodates long and high-volume hairstyles
• Roomy interior avoids crushing curls, braids, and blowouts
• Suitable for many textures: straight, wavy, curly, coily

How does the adjustable tie band keep the bonnet secure without discomfort?

YFONG uses a long elastic tie band made from a polyester-spandex blend for stretch and recovery without tightness. Fixed loops at the forehead let you anchor the tie or fashion a decorative bow while keeping the bonnet stable through sleep movement. The design balances hold and comfort so the cap won’t leave imprints or cause pressure points.

• Long elastic tie for customizable, gentle tension
• Fixed forehead loops provide secure anchoring and styling options
• Material blend ensures stretchiness with skin-friendly comfort

How durable and easy to care for is this silk sleep bonnet?

With both layers constructed from high-quality 6A 22-momme mulberry silk, this bonnet resists wear better than single-lined designs and delivers longer service with proper care. The double-layer build reduces abrasion points and helps the bonnet retain shape and smoothness over time. Follow gentle washing instructions to preserve the silk’s strength and luster.

• Double-layer construction enhances longevity and tear resistance
• High-grade 22-momme silk maintains sheen and strength with care
• Recommended: gentle wash, air dry, low-heat ironing if needed

Who this is for: This bonnet is tailored for anyone with long, dense, or textured hair who wants to protect styles overnight—women with waist-length or thick manes, people who sleep actively and need a secure cap, and those prioritizing hair moisture and reduced breakage. It also suits anyone switching from cotton caps or single-layer silk to a more protective, longer-lasting solution.
