100% Mulberry Silk Bonnet for Long Hair – Long Cap for Thick Curly Hair (SB28)

Give thick, full curls the space they need overnight.

The SB28 Long Sleep Bonnet is designed for hair that feels crowded, compressed or difficult to contain inside a standard round bonnet. Its approximately 50 × 33 cm elongated body provides more internal room for thick, dense and high-volume curls, coils and natural textures.

Made from Grade 6A 100% Pure Mulberry Silk, its single-layer construction feels light and smooth around the hair. The silk surface helps reduce the overnight friction that can contribute to frizz, tangles and disrupted curl definition, while a gathered ruffle edge makes it easy to slip on—no ribbons or knots required.

Why it works

Standard bonnets can feel too shallow when your hair is thick, long or naturally full. Packing too much hair into too little space may leave curls crowded and harder to refresh the next morning.

The SB28 combines a roomier long shape with a smooth silk surface to help:

• Reduce overnight friction, tangles and frizz
• Give thick curls, coils and natural textures more room
• Limit unnecessary crowding and compression
• Keep longer, fuller hair comfortably contained
• Protect curl patterns and styled hair from repeated pillow rubbing
• Make morning detangling and refreshing easier

No bonnet can guarantee completely frizz-free or perfectly unchanged curls. The SB28 is designed to reduce common sources of overnight disruption—not eliminate every factor that affects your hair.

Who it’s for

Choose the SB28 if you have:

• Thick or high-density hair
• Full curls, coils or natural textures
• Long curly or wavy hair
• Hair that expands, tangles or becomes puffy overnight
• A standard bonnet that feels too shallow or flattening
• A preference for easy slip-on wear without tie ribbons

Have long braids, locs, dreadlocks or extensions? Choose the 100% Mulberry Silk Long Bonnet with Adjustable Ties (SB20) if you want a more defined long body and an adjustable tie band.

Fit varies with head shape, hair length, density and hairstyle. The elasticated edge is designed for simple, secure wear but does not offer the same fit adjustment as a tie-band bonnet.

Supplier packaging is approximately 10 × 5 × 5 cm and 60 g, making the bonnet compact enough for storage or travel.

Most colour variants use the long silhouette shown in the main product images. Black Round Silk Cap is a separately named round style, so check both the colour and shape shown in the selected variant before adding it to your cart.

How to wear

1. Gather your hair loosely without pulling or compressing your curls.
2. Place the front edge comfortably along your hairline.
3. Pull the bonnet over the back of your head.
4. Guide your lengths and ends into the long body.
5. Check that all hair is contained and the edge feels secure, not uncomfortably tight.
6. Let the bonnet hang naturally rather than tightly folding your hair into the crown.

For very long curls, loosely sectioning or twisting the hair before placing it inside may make it easier to distribute the length evenly.

FAQ

What does Grade 6A Mulberry Silk mean?

Grade 6A is a recognised grading term used for high-quality mulberry silk fibre. The SB28 is made from Grade 6A 100% Pure Mulberry Silk rather than polyester satin.

Is the SB28 suitable for thick curly hair?

Yes. Its longer, roomier shape is intended for thick, dense and high-volume curls, coils and natural textures that can feel crowded inside a compact bonnet.

What size is the SB28?

It is a one-size bonnet recommended for an approximate head circumference of 54–62 cm. The elasticated opening measures approximately 56 cm relaxed and stretches to approximately 64 cm. The long bonnet body measures approximately 50 × 33 cm.

Does a silk bonnet completely prevent frizz or breakage?

No bonnet can guarantee completely frizz-free hair or prevent every type of breakage. However, the smooth mulberry silk surface helps reduce the overnight friction and pulling that can contribute to frizz, tangles, disrupted curl definition and stress on delicate strands.

Will it flatten my curls?

No bonnet can guarantee that curls will remain completely unchanged. The SB28’s generous shape gives fuller hair more room, helping reduce the crowding and compression that can occur inside a smaller bonnet.

Is the SB28 adjustable?

The SB28 has a gathered elasticated edge and does not have adjustable ties. If you prefer to control the fit with a tie band, consider the SB20 Long Bonnet.

Is the SB28 single- or double-layered?

The SB28 uses a lightweight single layer of pure mulberry silk with a gathered ruffle edge.

Should I choose SB28 or SB20?

Choose SB28 when your main concerns are hair density, curl volume, internal room and easy slip-on wear. Choose SB20 for long braids, locs, dreadlocks or extensions, or when you prefer an adjustable tie band.

What is the Black Round Silk Cap option?

It is a separately named round-shaped variant within the same product selector. It is not the long silhouette shown for most colours. Check the selected variant image and name carefully before adding it to your cart.

How do I wash it?

Hand wash in cool water no warmer than 30°C using a pH-neutral liquid detergent suitable for silk. Reshape and line dry in the shade. Do not bleach, wring or tumble dry.

Choose your colour and give thick, high-volume hair roomier overnight protection.
