The top 5 at a glance
A silk pillowcase goes on over an ordinary pillow just like a cotton one; the difference is the smooth, fine weave against your face and hair all night, which tugs less than cotton as you turn over. Silk is sold by weight, measured in momme: the higher the number, the thicker the fabric. Plain cases come in lots of colours; some come boxed, or with a matching eye mask.
Every case here is 100% mulberry silk, cut for the standard UK pillow size of 50 × 75cm. Silk asks for a little more care than cotton: a gentle wash, by hand or on a delicate cycle in a mesh laundry bag, and drying away from strong sun.
What matters
- “Satin” usually means polyester; look for 100% mulberry silk.
- 19 momme or more for most; 16 momme is lighter.
- Silk on the back as well as the front.
- A hidden zip rather than an open envelope end.
#1ZIMASILK 100% Mulberry Silk Pillowcase
£20–£30
- Silk on both sides
- Dyes made to hold colour
- 180-day quality guarantee
Both sides are 19 momme, grade 6A mulberry silk, so it doesn’t matter which way up it goes on, and a hidden zip keeps the pillow from sliding out. It comes in over 35 colours, and ZIMASILK guarantees it for 180 days against quality problems.
What owners say: Owners praise the quality and say their hair wakes up smoother and less frizzy. It washes easily and dries quickly.
A closer look: Momme is the silk’s weight, and ZIMASILK says its 19 momme is as thick as cases other brands sell as 21 or 22 momme, so don’t rule it out on the number alone. Its dyes are made to hold their colour through washing, which matters most with the darker shades.

#2ALASKA BEAR 100% Mulberry Silk Pillowcase
£20–£30
- OEKO-TEX certified silk
- Silk on both sides
- Hidden zip keeps pillow in
Double-sided 19 momme mulberry silk with a hidden zip and the inside edges stitched over for a neat finish, and it’s OEKO-TEX certified as made without harmful substances. The range of colours makes it easy to match to the rest of the bedding.
What owners say: Owners find it soft and beautifully made, with silk on both sides, and say it leaves hair less frizzy and helps with morning creases.
A closer look: It’s cut for a standard UK pillow, so check yours isn’t a king size before ordering, and the hidden zip at one end stops the pillow wriggling out overnight. Hand wash it in cool water with a mild detergent, or use the machine’s gentlest cycle.

#3vespersilk Mulberry Silk Pillowcase with Eye Mask
£20–£30
- Matching silk eye mask included
- 360-day quality guarantee
- Silk on both sides
The case comes with a matching eye mask in 100% mulberry silk, padded with light cotton, and a satin pouch to keep it in. Both sides of the case are 19 momme, grade 6A silk with a hidden zip, so it’s a full silk sleep set in one box.
What owners say: Owners find it comfortable and luxurious to sleep on and say it keeps hair smooth. Some think the fabric feels more like satin than silk.
A closer look: With an adjustable strap, the eye mask helps on bright early mornings, long flights or after a night shift, and the satin pouch keeps it clean in a carry-on between uses. Keep the order details, as the maker offers a 360-day guarantee against quality problems.

#4OLESILK 100% Mulberry Silk Pillowcase
£10–£20
- Silk on both sides
- Hidden zip keeps pillow in
- Lighter 16 momme silk
Mulberry silk on both sides, with a hidden zip, placed so the cold, hard zip doesn’t press into your face as you sleep, and it arrives in its own presentation box. At 16 momme it’s a lighter silk than the others here.
What owners say: Owners find it silky smooth, with less frizz and fewer tangles in the morning, and say it washes well and fits a standard pillow. Reports on the zip are mixed: some like it, others find it stops short of the end of the case.
A closer look: Hand washing is the gentlest option, but the most delicate machine cycle in warm water works too; skip the bleach, let it air dry and use only a cool iron if it needs one. Turning it inside out before washing helps protect the sheen.
Best for: No zip against the face

#5Ravmix 100% Mulberry Silk Pillowcase
£10–£20
- Heavier 21 momme silk
- Silk on both sides
- Hidden zip keeps pillow in
The silk is 21 momme on both sides, grade 6A mulberry, the heaviest weight on this list, with a hidden zip at one end so the pillow stays put. The care label allows machine washing, which suits anyone who won’t hand wash.
What owners say: Owners like the colour and the softness against the face, and say it helps stop frizz. A few question whether it’s pure silk, and the size doesn’t suit every pillow.
A closer look: Silk soaks up less than cotton, so night creams stay on the skin rather than in the pillow. Ravmix also says silk keeps you cool in summer and cosy in winter, so there’s no need to swap it for a cotton case when the seasons change.
Best for: Heaviest fabric
