The Best Travel Sleep Mask

Manufacturer-published listing specifications, compiled 17 October 2026. Only one of the three publishes a weight and none publishes a warranty term. Prices on the buy buttons are live.

Flat or contoured, and nothing else

Every sleep mask ever sold is one of two objects. A flat mask is a piece of fabric with a strap: it rests on your closed eyelids and your lashes. A contoured mask has molded cups that bridge over the eye socket, so the fabric touches your brow and cheekbone and nothing in between.

That is the whole decision, and it is not a matter of taste. If you sleep on your side, the pressure that squashes a flat mask into your eye comes from the pillow, not the strap. If you wear eye makeup, a flat mask takes it off. If you open your eyes under the mask — many people do, without noticing — a flat mask is fabric against an open eye.

The three, as published

The two numbers, and who publishes them

Cup depth is how far the molded cup stands off your eye. MZOO publishes 13 mm. That is the figure that decides whether your lashes brush the inside of the mask with every blink, and it is the specification most contoured masks simply do not print.

Nose padding is the depth of the foam that fills the gap beside the bridge of your nose. MZOO publishes 22 mm. Almost all of the light that reaches your eyes inside a mask comes through that gap, which is why a mask that fits your forehead perfectly can still be useless.

Manta publishes neither number. What it publishes instead is a mechanism: the eye cups detach and reposition, so the spacing is set to your face rather than to an average one. That is genuinely a different kind of answer, and it is the right one if fixed cups have never worked for you — but it is an answer you cannot check on paper before it arrives.

What each one costs you in a bag

Only Manta publishes a weight: 1.47 oz. In a category where the whole product weighs less than a bread roll, weight is not the constraint — thickness is. A contoured mask has rigid cups that do not compress; a flat silk mask folds down to the bulk of a handkerchief and can live in a jacket pocket rather than in the bag.

That is the real trade on this page. The contoured masks are better at the job. The flat mask is better at not being a thing you have to carry. If you are packing to a strict carry-on and the flight is three hours, the silk mask is a perfectly honest answer.

Which one, and who should skip it

• Most people, including side sleepers: MZOO. Published 13 mm cups, published 22 mm nose padding, published 19–28 in strap. Skip it if fixed cups have never sat right on your face, because these do not move.
• A face nothing fits: Manta. The cups detach and reposition, which nothing else here can do. Skip it if you want to know the geometry before you buy, because Manta publishes none of it.
• Minimum bulk: Alaska Bear silk. Skip it if you sleep on your side or wear eye makeup — see the skip note on its card below.
