MZOO 3D Contoured Sleep Mask

One Wirecutter tester called it perfect for a nap in a sunny window, and Caira Blackwell noted it stopped light at the nose bridge even lying on the side. The Guardian named it best overall out of 32 masks.

The flat silk design does not seal like a contoured cup, but Wirecutter reported all testers found it did a decent job of blocking light. The Guardian ranked it best budget.

MZOO 3D Contoured Sleep Mask

Wirecutter described the convex gap that lets your eyes open and close, ringed by memory foam that rests on the eye sockets, as especially comfortable. The Guardian praised the same roomy cups.

Wirecutter's Caira Blackwell called it comfortable, soft, and lightweight, popular with every tester regardless of sleep style. Both silk sides stay breathable against the skin.

MZOO 3D Contoured Sleep Mask

Wirecutter's side-sleeping testers, who usually struggle with masks, found this one stayed on all night. One tester said they preferred it to the Alaska Bear because it did not slip.

Several long-term Wirecutter testers reported it slipped off mid-night unless they retightened the strap every couple of nights, the one clear knock against it.

The foam cups run warmer than silk. Wirecutter rated it comfortable through the night, though hot sleepers may prefer the Alaska Bear's silk cover.

Wirecutter found the mulberry silk stays cool even pressed against skin all night, which is why it beats the foam picks for hot sleepers and long-haul flights.

MZOO 3D Contoured Sleep Mask

It is hand wash only, and Nidra's teardown blog flagged a 2 to 4 month lifespan on the cheapest foam cups, so replace it more often than a silk mask.

Alaska Bear Natural Silk Sleep Mask

It is hand wash only and the thin strap felt scratchy to some Wirecutter testers. Silk care keeps it going, but the strap is the weak point.

The Verdict

Our Bottom Line

The MZOO 3D Contoured Sleep Mask is the rare pick two independent panels put at the top. It was a Wirecutter top pick and the Guardian's best overall out of 32 masks tested across nine weeks. The reason is the molded eye cups. There is a convex gap so your eyes can open and close, ringed by memory foam that rests on the eye sockets, and one Wirecutter tester called it perfect for a nap in a sunny window. It drops the room into complete darkness the moment you put it on. What sealed it was the fit. Wirecutter's side sleepers, who usually give up on masks, found this one stayed on all night without light leaking at the nose bridge. All of that costs under twenty dollars.

The Alaska Bear Natural Silk Sleep Mask is Wirecutter's silky top pick for around fifteen dollars, and it wins on a quality the MZOO cannot match. The mulberry silk stays cool even pressed against skin all night, which is why Caira Blackwell's testers reached for it on long-haul flights and in warm rooms. It was popular with every tester regardless of sleep style, and the flat design lies flush on a pillow, so stomach sleepers can finally use a mask. The Guardian ranked it best budget. It does not seal like a contoured cup, but for hot sleepers and travelers it is the softer, cheaper, more forgiving choice.

Best for:
  • Hot sleepers who want cool silk against the skin
  • Stomach sleepers who need a mask that lies flat
  • Travelers who want soft silk for the price of a lunch
