OPEN YOUR EYES WITHOUT TAKING IT OFF

The reason a sleep mask ends up on your forehead somewhere over the ocean is that it is pressing on your eyelids. Two moulded cups sealing on the brow and cheekbone leave the eyes free, so the mask that is still on when you land is the one that never touched them.

  • Contoured cups, no lid contact — you can open your eyes underneath, which flat masks never allow
  • Memory-foam brow and cheek rim — seals on bone rather than pressing on soft tissue
  • Adjustable nose bridge — closes the gap under the nose where cabin light gets in
  • Mulberry silk face — does not drag at the temples the way a brushed synthetic does
  • Flat elastic strap with a slider — no buckle pressing on the skull against a headrest

Contoured eye cups mean nothing touches your eyelids, so you can open your eyes underneath it. That is the difference between a mask you wear for an hour and one you sleep in.

Nothing touches your eyelids

Flat masks press on the lids, which is why most people push them onto their forehead somewhere over the Atlantic. This one has two moulded cups with a memory-foam rim that seals on the brow and the cheekbone, leaving space in front of the eyes. The face side is mulberry silk, which is smooth enough not to drag on the skin at the temples, and the nose has an adjustable bridge to close the gap that lets light in from below. The strap is a flat elastic with a slider, not a buckle that sits against the skull.

Questions about the sleep mask

Does light still get in at the nose?
That is the usual failure and the reason for the adjustable bridge. Pinched to your own nose shape it closes the gap; on a very low bridge you may still see a sliver, which the strap tension takes out.

Will it work for a side sleeper?
The cups stand about 2 cm proud, so on a pillow the rim takes the pressure rather than your eye. It is deeper than a flat mask, which some side sleepers dislike on a soft pillow.

Is silk worth it over a synthetic?
For the face side, yes — it does not drag on skin at the temples when you turn, which is what wakes people. The structure comes from the cups and the foam; silk is about comfort, not blackout.

Questions about this one

How long does delivery take?

Standard shipping is free on every order with no minimum and arrives in 10–15 business days. Express is $59.99 and arrives in 5–9 business days.

Where do you ship?

The United States only, priced in USD.

Can I return something?

Will a packing cube fit my suitcase?

Every product page lists finished dimensions in both inches and centimetres. Measure the inside of your case rather than its external size — the shell and wheels are not usable space.

Is anything battery powered?

No. Nothing in the catalogue charges, pairs or tracks. Compression here is done by a second zip or a strap you pull by hand.
