Best sleeping mask I have ever had

I've really tried a lot of sleep masks, but this one is by far the best.

Super soft, you don't feel it at all, fits perfectly and it really darkens super. Perfect!

Best sleep mask ever

I've tried so many sleep masks from cheap to very expensive and was never satisfied.

This one is not only incredibly comfortable, but also pleasantly cool on the skin.

If I had one suggestion for improvement it would be that the elastic band should be adjustable in length.

Soft fabric

The fabric is very pleasant to the eyes. But had hoped for a slightly cooler effect. Darkens well in any case.

Great fabric, super soft and comfortable

It would be even better if the band could be adjusted individually. It sits a little too loose for me
