Manta Sleep Mask vs Ostrichpillow Eye Mask

The Manta wins because it is the only mask here where you position the light seal yourself, and it does it without any pressure on the eyelids. The Ostrichpillow is lighter, cheaper to live with and better documented, and for most sleepers it is close enough that the choice comes down to whether you want cups or a contoured bridge.

Manta Sleep Mask

Buy it

Detachable eye cups that slide along the strap, so you build the blackout seal around your own face instead of accepting an average one.

• The eye cups detach and can be placed anywhere along the head strap, which is the only real fix for a nose bridge that leaks light.
• The hollow cup design keeps all pressure off the eyelids and lashes, so you can blink with the mask on.
• Manta states the mask is machine washable in cold water inside a mesh laundry bag, then air dried flat.

• Manta does not publish the mask weight or its packed size anywhere on the product page.
• The cups add bulk, so this is the least pocketable mask of the four.
• The warranty against manufacturing defects runs six months, shorter than the two-year cover on the Ostrichpillow.

Ostrichpillow Eye Mask

Buy it

A 30 g contoured foam mask with every measurement published and a two-year warranty, which is more than most of this category manages.

• At 1 oz (30 g) it is the lightest mask here by a wide margin, and you stop noticing it within minutes.
• Ostrichpillow publishes the full size, 30 x 8.5 x 3 cm (11.8 x 3.4 x 1.1 in), so you can check it against your face before buying.
• Backed by a two-year warranty and 100-day returns, and it ships with its own pouch.

• The foam bridge is a fixed shape, so if it does not suit your nose there is no adjustment to make.
• Hook and loop closures collect hair and lint over time and get noisier as they age.
• The contoured foam is one piece with the fabric, so a worn spot means replacing the whole mask.
