Frequently asked questions
What does 22 momme silk mean?
Momme is the weight used to measure silk, and a higher number means a denser fabric. The Green Sapphire mask uses 22 momme mulberry silk over a padded core, so it feels soft and substantial against the face rather than thin.
Can I wash this sleep mask?
Yes. Drowsy describes the Green Sapphire mask as fully washable. Silk is a delicate fabric, so follow the care instructions that come with the mask each time, and give it a little time to dry before you wear it again that evening.
Does the mask block out light?
It is designed as a blackout mask. The padded silk panel sits across the eyes, and a fully adjustable strap holds it close, so the room goes properly dark whether the light is a streetlamp, a partner reading late or an early summer morning coming through the curtains.
Who makes this sleep mask?
The Green Sapphire mask is made by Drowsy, a brand that works in silk for sleep. Aetheo selects it for the Rest collection alongside other small objects for the end of the day, and delivery is free to any address in the United Kingdom.
