About this piece
A double-sided mask in 22 Momme Mulberry silk, filled with natural mulberry batting. The soft champagne band doesn't press.
22 Momme — explained
"Momme" is a Japanese unit that measures the density of silk. Below 16 momme silk feels thin and translucent; above 25 it becomes heavy and stiff. We choose 22 momme — substantial enough to drape elegantly and survive dozens of washes, light enough to let the skin breathe. It is the weight on which Como ateliers build their signature pyjamas.
Care
Hand-wash at 30°C with a gentle, pH-neutral detergent — or in a mesh bag on the wool cycle. Do not wring, do not tumble dry. Iron at low temperature on the inside. Store in a dark, dry place.
A sleep mask for deep sleep has to do two things: block every trace of light and disappear on your face. Light — even the little that passes through closed eyelids — suppresses melatonin and keeps you in the lighter stages of sleep. Our 22 Momme Mulberry silk mask brings complete darkness without pressing on the eye sockets, so you fall into deep sleep sooner and stay there longer.
Why darkness determines deep sleep
Your body clock reads light through the eyes, even when they're closed. A streetlight, a standby LED or an early summer sunrise keep the body in low-level alertness. A mask that truly seals extends the time you spend in deep, slow-wave sleep — the restorative stage. Our double layer of 22 Momme silk with a contoured edge closes along the bridge of the nose, exactly where most masks leak light.
No pressure on the eyes, no marks in the morning
Tight elastics and stiff foam press on the eyeball and wake you at every turn. Our mask is filled with natural mulberry batting and held by a wide, adjustable silk band that spreads the weight across the back of the head. You stop noticing it within a minute — and wake without red lines or puffiness.
Silk instead of cotton or satin
Cotton pulls moisture from the thin skin around the eyes; polyester satin traps heat and makes you sweat. 22 Momme Mulberry silk is temperature-regulating, hypoallergenic and barely absorbent, so your night cream stays on the skin instead of soaking into the fabric. It's also why a silk sleep mask is so often recommended for a sensitive or dry eye area.
For travel, shift work and light sleepers
Sleeping during the day after a night shift, or on a plane and in hotel rooms where you don't control the light? The mask does the job blackout curtains do at home. It weighs almost nothing, folds flat into its silk pouch and holds its shape, even after dozens of hand washes.
Does a sleep mask really help you sleep more deeply?
Darkness is one of the strongest cues for your sleep rhythm. Removing residual light helps you fall asleep faster and stay longer in the deep stages. The effect is biggest in bedrooms you can't fully darken.
Is 22 Momme silk better than satin for a sleep mask?
Satin is a weave, not a fibre — usually polyester. 22 Momme Mulberry silk is a natural fibre that breathes, regulates temperature and absorbs far less. More comfortable on the skin and longer-lasting.
How do I wash my silk sleep mask?
By hand in cold water with a pH-neutral soap, don't wring, dry flat out of direct sunlight. That keeps the silk's lustre and loft for years.
