Looking after it

Cold water, 30 degrees or below, hand wash or a gentle machine cycle in a mesh bag. Use a detergent with no enzymes and no bleach. Air dry out of direct sun and keep it out of the dryer. Iron on the lowest setting, on the reverse, if you iron it at all.

22 Momme MulberryThe same silk as the pillowcases
One SizeElasticated band
For Wrapped HairAn alternative to changing the bedding
Hand WashCold, enzyme-free, shade dry

22 momme mulberry silk, one size, elasticated.

A sleep cap in the same silk as the pillowcases, for people who would rather wrap the hair than change the bedding.

A silk bonnet does the same job as a silk pillowcase and does it whichever way you turn in the night. That is the whole argument for it.

One size, held by an elastic band. It is not adjustable, so if you have a lot of hair to get inside it, that is worth knowing before you order.

The same 22 momme mulberry silk as the pillowcases, so it behaves the same way against hair.

It will not grow hair and it will not repair it. What it does is give hair a smoother surface to move against than cotton, and we would rather say that plainly than sell it on anything else.

Silk Bonnet

The case for a bonnet over a pillowcase is coverage. A pillowcase only helps where your head is; a bonnet travels with you.

Silk Bonnet

The case against it is that some people cannot sleep in one, and there is no way to know which you are until you try. It is cheap enough to find out.

Silk Bonnet

At 22 momme this is the heavier end of silk, which is why it holds its shape rather than collapsing on the head.

Silk Bonnet

Wash it the way you would wash the pillowcases: cold, no enzymes, no bleach, no dryer, dry in the shade.

Not sure yet? That is fine.

You can change your mind. You have 15 days from purchase on any unused item in its original packaging. That sits on top of the 14 day right to cancel that UK law gives you on anything bought online. On a cancellation you pay only the direct cost of sending the goods back.

If it turns up faulty, damaged or not as described, that is on us. Under the Consumer Rights Act 2015 you are entitled to a repair or a replacement first, and to a price reduction or your money back where that does not put things right. We pay the return postage and nothing on this page limits any of it. Read the detail on our refunds and returns page, or ask us anything before you order.

Frequently Asked Questions

Can a Silk Bonnet help preserve blow-dry styles?

A Silk Bonnet preserves blow-dry styles by shielding hair from friction that flattens volume overnight. The smooth fibres maintain bounce and shape, reducing the need for extra heat styling in the morning.

Why are Mulberry Silk Sleep Caps popular worldwide?

Mulberry Silk Sleep Caps are popular globally because of their proven benefits for hair health.

Can a Silk Bonnet make morning routines quicker?

Hairstyles require less restyling, saving time and energy, while keeping hair looking polished and ready for the day ahead.

Why are Mulberry Silk Sleep Caps seen as sustainable?

Mulberry Silk Sleep Caps are sustainable because silk is biodegradable and eco-friendly. Unlike synthetic fibres, silk production has a smaller environmental impact while delivering luxury and functionality.

Does a Silk Bonnet help reduce hair shedding?

A Silk Bonnet helps reduce shedding by minimising overnight tugging. By decreasing mechanical stress, it allows hair to retain strength and length, especially important for textured or fragile strands.

Can Silk Bonnet Hair support protective styles overnight?

Silk Bonnet Hair protection keeps braids, twists, and locs neat overnight.

How does a Mulberry Silk Sleep Cap compare to satin alternatives?

A Mulberry Silk Sleep Cap outperforms satin alternatives because silk is a natural protein fibre. It offers superior breathability, durability, and moisture control, giving hair long-term protection and comfort.

Is a Silk Bonnet good for preventing breakage in fine hair?

A Silk Bonnet is especially good for fine hair, which is more prone to snapping. The soft silk surface prevents stress on delicate strands, allowing them to remain stronger and healthier.

Why do experts recommend Mulberry Silk Sleep Caps?

Experts recommend Mulberry Silk Sleep Caps for their high-quality long fibres, which are smoother and more durable than regular silk. This premium weave ensures lasting protection and enhanced hair health.

Can a Silk Bonnet reduce hair tangling?

A Silk Bonnet reduces tangling by keeping strands aligned through the night. This saves time in the morning routine, as detangling becomes quicker and less damaging to fragile ends.

How does Silk Bonnet Hair care fit into a luxury routine?

Silk Bonnet Hair care elevates a routine by combining beauty with wellness.

Why is a Silk Bonnet considered anti-static?

A Silk Bonnet is considered anti-static because its natural proteins minimise friction that causes flyaways. Unlike synthetic fabrics, silk prevents hair from clinging, leaving it sleek and manageable.

How does Silk Bonnet Hair care support chemical-treated locks?

Silk Bonnet Hair care supports chemically-treated hair by minimising dryness.

Can a Mulberry Silk Sleep Cap improve scalp comfort?

A Mulberry Silk Sleep Cap improves scalp comfort by balancing airflow and retaining natural oils. This prevents irritation and dryness, making it ideal for sensitive skin and long overnight wear.

Does a Silk Bonnet protect against pillow friction?

A Silk Bonnet protects against pillow friction by creating a barrier between hair and rough fibres. This decreases tangling and breakage, ensuring strands stay smooth and nourished every morning.

Why is Silk Bonnet Hair ideal for braids and extensions?

Silk Bonnet Hair care is ideal for braids and extensions, preventing snagging and prolonging neatness. Silk's smoothness ensures tension styles last longer, reducing the need for constant salon maintenance.

Is a Mulberry Silk Sleep Cap suitable for travel?

A Mulberry Silk Sleep Cap is perfect for travel as it packs light and keeps hairstyles fresh across time zones. It protects against harsh hotel linens, helping travellers maintain sleek, manageable hair.

How does a Silk Bonnet support natural hair growth?

A Silk Bonnet supports growth by minimising mechanical damage during sleep. By reducing tangling and shedding, it allows hair to retain length while safeguarding scalp oils that nurture healthy development.

Why is a Mulberry Silk Sleep Cap considered breathable?

A Mulberry Silk Sleep Cap is breathable because silk regulates temperature naturally, keeping hair cool in summer and warm in winter. This balanced airflow ensures comfort without overheating during sleep.

Does a Silk Bonnet help extend salon results?

A Silk Bonnet helps extend salon results by maintaining smooth finishes for longer. By reducing hair shaft stress overnight, it prolongs blow-outs, straightening, or professional treatments without added heat damage.

How does Silk Bonnet Hair care help men's grooming routines?

Silk Bonnet Hair care benefits men by preserving waves, braids, and fades overnight.

Is a Silk Bonnet useful for people with curly or textured hair?

A Silk Bonnet is highly beneficial for curly or textured hair, preserving definition and reducing tangles. Silk's smooth weave supports coil retention, making it easier to maintain natural volume without breakage.

How does a Mulberry Silk Sleep Cap benefit skin as well as hair?

A Mulberry Silk Sleep Cap benefits both hair and skin by reducing friction on pillow contact.

What makes a Silk Bonnet essential for nightly hair care?

Its smooth fibres keep hairstyles intact while locking in natural moisture overnight.

How much is delivery?

Free across the UK on orders of £60 or more. Below that the method offered is Express Delivery at £22, which is also available above the threshold as a paid upgrade. Allow 5 to 7 days after a 24 to 48 hour handling time.

Do your prices include VAT?

Yes. Every price shown on this site includes VAT, so the figure on the product page is the figure you pay. Nothing is added at the checkout.

Is everything on this site actually silk?

No, and the page always says which. The mulberry range is 100 per cent silk. The satin range is a polyester or viscose blend woven in a satin weave, which gives a similar glide at a much lower price and washes far more easily. Both are on the site on purpose and each product page states its own fabric.

What does momme actually measure?

Weight, not thread count. Silk thread is too fine to count usefully, so it is weighed instead: momme is the weight in pounds of a 45 inch by 100 yard piece. On this site the pillowcases, bonnet and baby mittens are 22 momme, the silk flat sheet and the men's silk pieces are 19 momme, and the women's mulberry pyjama set is 16 momme.

How do I wash silk without ruining it?

Cold water at 30 degrees or below, by hand or on a gentle machine cycle in a mesh bag. Use a detergent with no enzymes and no bleach. Do not tumble dry it and do not use fabric conditioner, which sits on the fibre and dulls the surface. Dry in the shade and iron on the lowest setting, on the reverse.

Can I return it if I change my mind?

Yes. UK law gives you 14 days from delivery to cancel an online order for any reason under the Consumer Contracts Regulations 2013, and this shop allows 15 days on an unused item in its original packaging. The one exception is the embroidery service, because a personalised item is made to your own specification.

Not sure which one you need?

Tell us what you want it to do and how you do laundry, and we will tell you whether the silk or the satin is the better spend. Free delivery across the UK on orders over £60.
