Manta Sleep Cotton Mask - 100% Blackout Eye Mask - Zero Eye Pressure - Adjustable Eye Cups - Guaranteed Deepest-Possible Rest - Perfect Sleeping Mask For Light Sleepers, Travelers, Midday Nappers

Pricey, but the only sleeping mask that ensures total darkness with comfort.

Definitely eye shutout/blackout. No discomfort. Amazing feel.Awesome Sleep mask.

Have tried so many sleep masks. This one is by far the best. Have purchased 4 of these in the past 3 months. It is expensive but the quality of sleep I derive from it is Incredible.

Get the newer improved version with better side sleeping design. This one is top notch in terms of light blockage but uncomfortable and light friendly when sleeping on the side.

I bought this from the Manta website years back. Happy to see it on Amazon now. It's expensive, yes, but it's VERY effective. I've faced zero light leakage and it's the only eye mask that lets me open my eyes or blink inside the mask. My only advice is to wash it regularly. Once a month, probably. The mask comes with a mesh pouch that you can chuck into the washing machine. If you don't wash it, the grey part of the mask will get quite dirty. I'm facing this problem.

does not fit properly

I sleep on my back and it works perfectly for me.Good quality Velcro, adjustable soft eye cups and once you find the right fit you are completely blacked out.It definitely slips or moves around if I side-sleep or sleep on my stomach.Finally, it is a great product for travellers, back-sleeper,
