Why light matters
Even a little light thins your sleep.
Your body reads light as 'morning' and starts winding down melatonin — the hormone deep sleep depends on. Even a sliver through the curtains or a partner's lamp can pull you out of deep sleep without fully waking you. Block the light and your natural melatonin can do its job. Cheap foam masks slip, press on your eyes, and crush your lashes. Silk solves all three: it blocks the light, sits weightless, and glides over your skin.
- 100% Blackout when it fits right
- 22 Momme — dense, opaque weave
- 6A Highest mulberry silk grade
- 0 Pressure on your eyes
Why this mask
Four reasons it earns its place.
Kind to skin + lashes.
Silk's smooth surface won't tug your lashes or crease delicate eye skin the way foam and elastic do — naturally gentle on sensitive skin.
Breathable + cool.
Mulberry silk is naturally temperature-regulating, so it never feels hot or clammy against your face.
Built to last.
22-momme weave is dense and durable — it survives the wash and keeps its shape, season after season. Certified to OEKO-TEX Standard 100, so nothing harmful sits against your skin.
The silk
Real mulberry silk. Not 'silk-like'.
Most 'silk' products are polyester satin, or thin low-momme silk that frays fast. Ours is 22-momme, 6A-grade, 100% mulberry silk — OEKO-TEX Standard 100 certified — and you feel the difference the first night.

Dense where it matters — 22 momme.
Momme measures silk's weight and density. At 22 momme this is substantial, opaque, durable silk — dense enough to block light completely, not the thin, slippery stuff that frays in a season.

What's in it

The highest grade of silk — long, uniform 6A-grade fibres. No blends.
22-momme weave
Dense and opaque. Heavier than the 16–19 momme most 'silk' products use.
OEKO-TEX Standard 100

What's never in it
Polyester 'satin'
The fake silk most cheap masks/cases use. Doesn't breathe, doesn't last.
Silk-one-side blends
Some sell cotton-backed 'silk'. Ours is real mulberry silk both sides.
Harsh dyes & finishes
Excluded by the OEKO-TEX Standard 100 certification.
A better way to block the light.

Darker nights, happier mornings.

Total blackout, finally.
I've tried six masks. This is the first that actually blocks everything and doesn't press on my eyes. Travel essential now.

So soft I forget it's on.
No more morning lash damage or red marks. It's like nothing's there but the room is pitch black.

Lovely gift, lovely quality.
Bought the Leopard print for my sister. The silk feels genuinely premium, not the thin stuff you get cheaper.

Night-shift saviour.
I sleep days. This plus blackout blinds and I finally get proper rest. Stays put when I turn over too.

Got questions?
The honest answers.
What does '22 momme, 6A grade' actually mean?
Momme measures silk's weight and density — 22 is the sweet spot for sleep silk: dense enough to be opaque and durable, still soft and breathable. 6A is the highest grade of mulberry silk, meaning long, even, high-quality fibres. Together they're what separates real silk from thin, slippery imitations.
Will it actually block all the light?
Yes — the contoured shape and dense 22-momme weave block light edge to edge when adjusted to fit. It's designed to sit flush around the nose, the usual gap on cheap masks.
Will it fit me? Is it adjustable?
It's one size, and it fits just about everyone — there's nothing to adjust. The soft elastic band is longer and more generous than most masks (it stretches to around 32 inches / 81 cm), so it sits gently on bigger and smaller heads alike. No buckle, no fastening, no notches — just a pressure-free hold.
Is it good for side sleepers?
It is — it's flat and lightweight with a soft, longer elastic band and no buckles or hardware to press into the pillow, so it stays comfortable and in place however you turn.
How do I wash it?
Hand wash in cold water only, with a mild pH-neutral detergent. No bleach, no fabric softener, no tumble dryer — air dry in the shade. It'll keep its softness for years (and it's the care your 12-month warranty asks for).
Is silk really better for my skin?
Silk's smooth surface creates less friction than cotton or foam, so it's gentler on the delicate skin around your eyes and won't tug your lashes. We'll leave the bigger beauty claims to others — but the comfort difference is real and immediate.
What if I don't love it?
Two layers. 60 nights to love it — sleep in it, and if it's genuinely not for you, talk to us and send it back for a refund of the product price. And a 12-month warranty against manufacturing defects (seams, stitching, the band) — replaced free with just a photo. Email support@thesleepguard.com either way.
