This guide focuses on Promeed’s 23-momme zippered silk pillowcase. It is based on the seller’s published information, not a new wash or sleep test. Other Promeed bedding may use different materials and terms.
What do 23 momme and mulberry silk mean?
Promeed describes the referenced case as 100% mulberry silk with a zipper. Momme is a measure of silk fabric weight, not a measurement in millimeters. A heavier fabric can feel different, but the number alone does not guarantee softness, durability or performance.
Check whether the stated fiber content applies to both sides and which size you are ordering. Silk is animal-derived; a polyester satin pillowcase is a different material for those who prefer to avoid animal products.

What comes with the case?
The current single-case listing describes one pillowcase, a fabric sample and a mesh laundry bag. The two-pack listing describes two cases with one sample and one bag. Promeed lists standard, queen and king options and a range of colors, although availability can change. Check the listing for your selected size and package rather than assuming every version contains the same extras.
How to choose the right size and closure
Measure your pillow across its length and width, then compare those measurements with the seller’s size chart. If the pillow is very full, allow enough room to insert it without pulling hard on the zipper or compressing the fill. A case that is too large may bunch under your face; a very tight one can change how your pillow feels.
The zipper helps keep the pillow enclosed, while an envelope closure is an alternative if you prefer a flap. Neither closure by itself determines the fabric’s quality. Look for smooth seams, check the zipper gently after delivery and verify whether the same fiber is used on both sleeping surfaces.
Understanding the fabric description
Mulberry silk describes a silk fiber; satin describes a smooth weave or finish and can be made with several fibers, including polyester. Check the fiber label if you are comparing a less expensive satin case to silk. A silk case and a synthetic satin case can both feel smooth, but their care, price and fiber content differ.
Momme is a fabric weight measure. It can help compare silk weights when other details are similar, but it does not tell you whether a particular case will feel right or how long it will last. Weave, stitching, washing, pillow fit and daily use all matter too.
What can a smooth pillowcase do?
Some people find a smooth surface helps reduce friction against hair. The American Academy of Dermatology suggests silk or satin coverings as one option for preserving curly styles. Results vary, and silk does not guarantee less breakage, clearer skin or better sleep.
The previous version of this review gave a precise customer-satisfaction figure without a verifiable source. It should not be used to predict your result. Silk can feel comfortable on skin, but it is not established as a treatment for acne, wrinkles or allergies.
Hair: what to expect in practice
If your goal is to preserve a hairstyle overnight, a smooth case is one option alongside a bonnet, scarf or other routine that works for you. The American Academy of Dermatology includes silk or satin coverings in its curly-hair advice. People with different hair textures and styling products may notice different results; a pillowcase is only one part of a hair-care routine.
Compare the case over several nights rather than relying on how slippery it feels in your hand. Consider whether your head stays comfortably on the pillow, whether hair products transfer onto the fabric and how often you need to wash it. If irritation develops, stop use and consider the fabric or laundry product as a possible factor.
Skin and temperature claims
Some people enjoy the feel of a smooth case on their face. That is a comfort preference, not proof that silk prevents wrinkles or treats acne. Keep pillowcases clean, use products appropriate for your skin and consult a clinician for persistent skin problems. A fabric certification has a specific scope and is not a guarantee of no reaction.
Silk may initially feel different from cotton or polyester, but room temperature, bedding and personal preference all influence overnight comfort. Do not expect a pillowcase to act as an air conditioner or solve night sweats.
Care and certification
Promeed’s referenced listing describes a delicate cold machine wash in a mesh bag and cold air drying. Follow the label supplied with your case; care can differ across products. Avoid assuming a generic silk routine is appropriate for every item.
The listing makes an OEKO-TEX STANDARD 100 claim. Check the current certificate and its scope for the item. Certification tests against specified criteria; it does not mean the fabric contains no chemicals or cannot cause a reaction in any individual.
A simple wash routine
Promeed’s current instructions specify cold water, a delicate cycle, a mesh bag and cold-air drying. Its care guidance also recommends closing the zipper and turning the case inside out before washing. Separate it from items with hooks, rough fasteners or other surfaces that could snag the silk. Use a detergent appropriate for silk and follow both the case’s label and detergent directions.
Do not use high heat simply to speed up drying. Let the case dry fully before putting it back on the pillow. If you prefer a spare case while one is being washed, compare the cost of an individual case with a two-pack. Care instructions may change, so the label supplied with your item takes priority.
Compare before buying
Compare the exact size, silk weight, fiber content, closure, total price and return eligibility with another silk case or a smooth synthetic satin case. A higher momme number alone is not proof that a product is better for your hair or will last a set number of years.

Who should consider it?
- Consider Promeed if you want a zippered silk case, are comfortable with delicate laundering and value the included mesh bag.
- Consider polyester satin if you want a smooth, animal-free surface and a different price or care profile; check the actual fiber label.
- Consider cotton if easy laundering and a familiar cotton feel matter more than a silky surface.
Promeed’s product listing advertises a 60-day return guarantee for direct purchases. Verify the current conditions, eligibility of used bedding, return costs and start date before ordering. A purchase from another seller is governed by that seller’s terms. Yawnder’s own bedding policy may differ from the manufacturer’s direct offer.
Compare single-case and multi-pack prices for the same size and include shipping or discounts that actually apply at checkout. A price difference can reflect fabric, package size, brand, construction or promotion; it does not establish which case will work better for your hair.
Common questions

Can I machine wash it?
The referenced listing allows a delicate cold wash with a mesh bag. Follow the label on your exact item.
Is the case silk on both sides?
Promeed describes the referenced zippered case as mulberry silk on both sides. Confirm the current label and listing for the exact version purchased.

Can I put it in a hot dryer?
Promeed specifies cold-air drying for the referenced case. Follow your item’s care label and avoid high heat.
