The problem with most bonnets is not the silk. It is staying on. Two long mulberry silk ribbons let you set the hold yourself and tie at the nape, where a pillow cannot push the cap off. Nothing has to be tight to stay put until morning.

Thoughtfully detailed to elevate your beauty sleep, the mulberry silk night cap wraps your locks in an unhurried embrace of pure elegance.
Smooth mulberry silk helps hair glide instead of catching, supporting less overnight frizz, fewer tangles, and reduced friction-related breakage.
The adjustable ribbon tie lets you secure the bonnet gently around the hairline, helping it stay comfortable through the night without feeling tight.
OEKO-TEX certified mulberry silk is tested for harmful substances, making it suitable for nightly contact with hair and delicate skin.
The smooth silk surface helps hair glide while you sleep, reducing friction that can cause tangles, frizz, flyaways, and fragile ends.
Mulberry silk absorbs less moisture than many common fabrics, helping hair keep more natural hydration and feel softer by morning.
Silk helps limit excess moisture on the sleep surface, supporting a cleaner-feeling bonnet and helping protect hair from dust mites between washes.

Before You Buy
The ribbon closes at any width. Nothing has to stretch.
There is no fixed size to get wrong. The ribbons close at whatever circumference suits you, so a smaller head is not left loose and a larger one is not squeezed. If a bonnet has ever given you a headache, that was the elastic, not the size.
Gather hair loosely at the crown first. The cap holds shoulder length through mid back hair coiled softly rather than packed in. Hair past the waist sits better in the Mulberry Silk Cap for Long Hair, which is cut deeper.
Three Steps
Gather, loosely
Hair to the crown, loose rather than tight. A small cushion of hair is what keeps the cap from sliding back.
Set it back
Sit the cap about a finger's width behind the hairline, not on it.
Tie at the nape
Not the forehead. A knot at the back sits below the point where a pillow lifts the cap away.
One more thing that helps, and it is not the bonnet: cotton grips silk and pulls the cap off through the night. On a silk pillowcase the two surfaces slide instead of catching.
Nothing has to be tight to stay put
19 momme mulberry silk, woven rather than printed.
Satin describes how a fabric is woven, not what it is made of. Most bonnets sold as satin are woven polyester. This one is 100% mulberry silk, a natural protein fibre.
Momme is how silk is weighed. 19 momme is the working weight for something worn on the head: heavy enough to hold its shape and survive washing, light enough that it does not sit warm. Our pillowcases go heavier at 22 momme, because a pillowcase is lain on rather than worn.
Polyester holds heat and moisture against the scalp. That is usually why a bonnet gets pulled off at two in the morning.
Mulberry silk is a breathable protein fibre that moves moisture rather than trapping it, so it stays closer to skin temperature. If you sleep hot or wake with night sweats, that is the difference worth paying for.
By hand, the gentlest way
Cool water, a mild detergent made for silk or wool, no bleach, no wringing. Press the water out in a towel and line dry away from direct sun.
Can it go in the machine
Yes, with care. A mesh bag, the delicate or wool cycle, cool water, lowest spin. Never tumble dry. It is harder on silk than hand washing and will shorten the life of the cap, but one careful cycle will not ruin it.
The first morning
Less tangling, and hair that combs out with fewer catches.
After two to three weeks
This is where people notice condition: smoother ends, less frizz along the lengths.
Where it shows least
A bonnet works by reducing friction. On coarse or short hair that does not tangle much to begin with, the difference will be quieter. That is an honest limit of what silk does.
Answers about sleeping in a silk bonnet, frizz protection, fit, and how to care for an adjustable ribbon tie cap.
Not if it is real silk. Polyester satin traps heat and moisture against the scalp, which is the usual reason a bonnet comes off in the night. Mulberry silk is a breathable protein fibre that moves moisture instead of holding it, so it stays closer to skin temperature.
Yes, with care, although hand washing is gentler. Use a mesh laundry bag, the delicate or wool cycle, cool water and the lowest spin setting, and never tumble dry. Machine washing shortens the life of the silk, but one careful cycle will not ruin it.
Absolutely. Making a silk sleep cap part of your nightly routine drastically minimizes friction, which safeguards your hair's cuticles against damage caused by cotton pillowcases. This consistent protection locks in essential hydration, extends the life of your blowouts or defined curls, and helps prevent split ends over time.
A genuine 100% mulberry silk head cap is the premium choice. While "satin" merely describes a synthetic weave (usually polyester), authentic silk is an organic, amino-acid-rich fiber that naturally breathes. To eliminate morning frizz and static, it provides a superior low-friction surface that keeps strands calm and highly hydrated.
Always ensure your strands are dry or slightly damp before putting them inside. Soaking wet hair is highly fragile, and trapping excessive moisture inside a dense night cap can compromise both cuticle strength and the delicate structure of the textile. For optimal results, let your hair air-dry or blow-dry most of the way first.
Utilize the adjustable ribbon ties to create a stable, personalized embrace around your hairline. Gently scoop your locks into the crown, then tie the flowing ribbons smoothly at the nape or side of your neck. If you experience shifting, positioning the band slightly over the ears or securing smooth sections with a flat clip can add stability.
Never. An evening cap should provide gentle containment, not pressure. If you notice tension, headaches, or elastic marks left on your forehead, simply loosen the adjustable wrap. The ultimate goal is a weightless, relaxed fit that stays positioned through the night without disturbing your sleep comfort.
We recommend laundering it once a week—or more frequently if you regularly apply heavy overnight oils, leave-in serums, or styling creams. Hand wash in cold water using a pH-neutral, silk-friendly detergent. Avoid twisting, never use bleach, and line dry in the shade to maintain the smooth, luminous charm of the fabric.
