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 if you iron it at all.

About this product

Cut with room for all of it.

100 per cent mulberry silk at 22 momme, one size, designed with enough volume for long hair, braids, weaves, rollers and an up-do without flattening any of them.

The two things people want from a bonnet are that it holds all their hair and that it is still on in the morning. Most fail one or the other.

This one is cut with volume rather than as a close cap, so long hair, braids, weaves, rollers and an up-do all go in without being pressed flat.

The silk is 100 per cent mulberry at 22 momme. A bonnet made from a polyester satin does part of the job.

It also keeps hair oils off the pillow, which is the quiet argument for a bonnet even if you already sleep on silk.

One size, and no sizing chart to get wrong.

A bonnet and a silk pillowcase solve overlapping problems and people often own both. The pillowcase takes the friction out of the surface. If you are choosing one, choose by hair length and by how much you move in your sleep.

The design decision that matters here is volume. A cap that fits closely flattens a style, and a bonnet that flattens a style gets taken off at 2am and does nothing at all. This one is cut deliberately roomy.

The band has to hold without gripping. Too tight and it leaves a line and presses on the hairline; too loose and it is on the floor by morning.

Care is the standard silk routine: cold water, enzyme-free detergent, no bleach, dry in the shade, no dryer.

Still deciding?

Not sure yet? That is fine.

You can change your mind. You have 15 days from delivery on any unused item in its original packaging. That sits on top of the 14 day right to cancel that Irish 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 2022 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

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. Our pillowcases, eye mask, bonnet and baby mittens are 22 momme, the silk flat sheet is 19 momme and the women's mulberry pyjama set is 16 momme.

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.

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.

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.

Is everything on this site actually silk?

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

Does a Silk Bonnet help extend salon results?

A Silk Bonnet helps extend salon results by maintaining smooth finishes for longer.

How much is delivery?

Free across Ireland on orders of €60 or more. Below that the method offered is Express Delivery at €25, 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.

The complete guide

Bonnet or silk pillowcase, and how to choose

4 min read Flair Silk Company

They are not the same fix

A silk pillowcase changes the surface your hair moves against. A bonnet stops the hair moving so much in the first place. Plenty of people use both, and that is not overkill.

Volume beats fit

The single reason a bonnet ends up in a drawer is that it flattened the style it was bought to protect. Look for one cut with room rather than one cut close. This one is deliberately roomy, which is also why it takes rollers and clamps.

The band decides whether you keep wearing it

Too tight and it marks the hairline. Too loose and it is off by morning. If a bonnet has ever left a line on your forehead, that is the thing to check before the fabric.

Silk against satin

A polyester satin bonnet glides in much the same way and costs less. If you use leave-in product, the silk is the one worth paying for.

Washing it

What it will not do

It will not make hair grow and it will not repair damage that is already there.
