It darkens everything to the maximum. Because of its thickness, you can't sleep on your side or on your stomach.

I sleep on my sides, so it's was a little uncomfortable at first, because the mask's bulkiness doesn't allow my head to fully rest on it's side.

But after a couple of weeks, it doesn't bother me anymore and I'm glad I stuck with it. This is the best sleep mask I've ever tried, in terms of blocking light.

No harsh, cold, morning light can reach my sensitive eyeballs with this baby on. Bonus points for the sturdy, adjustable head strap!

Honestly, I am amazed by the product. I work night shifts during the season and when I return, the room is all bright. As soon as I put on the mask, not a trace of light gets through. It fits the face perfectly, I have used other masks in the past and they were terrible, this one is a godsend. Even if it cost 100 euros, I would buy it

It was particularly convenient for me in the hospital. And it didn't bother me when sleeping on my side as the material is very soft.

I sleep excellently with this mask. Absolute darkness. It presses a bit on my nose, but I have a hooked nose, so never mind. Maybe people who sleep on their stomachs might have an issue.

very comfortable mask with an excellent feeling on the eyes. I didn't use masks because I didn't like how the fabric felt on my eyelids, but I use this one all the time when traveling.

one of the best and most versatile purchases I have made for travel and not only, you sleep and the whole world goes dark, without the elastic bothering your head

It makes day into night, the sun hits you in the face and you don't feel a thing. For sleep, it is much more comfortable compared to other masks, it stays well on the face.

Very good quality. The comment mentioned by other users, that is, when someone sleeps on their side the bulk of the material presses and this is somewhat uncomfortable, is indeed true - however, it is reduced when the pillow is soft and thus the head sinks more easily. In general, I have tried quite a few, and this is the best I have found so far.

Excellent sleep mask. Due to the cushions, it is not comfortable for sleeping if someone sleeps on their side. I mainly use it on the plane, where it is convenient because it does not let any light in at all.

The mask is only comfortable when lying on your back; if you turn to your side, it's not comfortable, and as for lying face down, that's out of the question. This mask is for traveling, to sleep sitting up in a plane, bus, ship, or car. The only thing I liked was the materials, which are of good quality, and that no light gets through at all

Good product made from pleasant and soft materials and the strap is adjustable.

If you want no light to pass through at all and not to press on your eyes, it is ideal.

The only thing is that it has two drawbacks: the cord may bother your ears and if you get hot, the area covered by the mask may sweat.

(I sort of solved both problems by loosening the strap a lot so that it doesn't bother the ear and there is a bit of space for air to circulate inside the mask, and at the same time no light passes through.)

nice feeling, better coverage than the simple ones. just the string is a small annoyance, as all masks have

Very good sleep mask for those who sleep on their back. It is not recommended for those who sleep on their side.

The only one I have tried that provides complete blackout; if you are particular about sleep and don't want even the slightest ray of light, this specific mask is the solution! Very good material quality, the foam is soft, best for lying on your back or slightly on your side.

100% worth its money, the mask. It doesn't make you hot, it doesn't stick to your eyes, the strap tightens just right and because I sleep at 7-8 in the morning due to night work, it's the best!

Very good construction material, very good fit on the face and complete blackout. Unfortunately, however, it must have been designed for sleeping in an airplane seat rather than in a bed, as the construction with the bulge is bothersome during sleep, especially if one prefers to sleep on their side or stomach.
