Hair genuinely less frizzy
Bought one to see what the fuss was about. Two weeks in and my blow-dry survives the night. Cool against the skin too, which I didn't expect to care about but do.

Save 25%The pillowcase your skin and hair spend a third of their life on. Woven from long-strand mulberry silk, it creates far less friction than cotton, so you wake with fewer sleep creases and less bed-head frizz. Silk also holds onto less moisture than cotton, which means the products you apply at night stay on your skin rather than soaking into your pillow.

The envelope closure keeps the pillow tucked in with no exposed zip against your face, and the standard UK size fits most pillows. Machine washable on a cool delicate cycle, so it stays an everyday essential rather than a special-occasion one.

Feels far more expensive than it is. The envelope closure keeps the pillow in place and it washes well on the delicate cycle in the laundry bag.
Beautiful to sleep on. Only note is the ivory shows skincare marks quicker than my slate one, so wash day comes around sooner.
