Sleep Eye Mask, Upgraded 3D Blackout Design, Ideal for Side Sleepers

The material is NOT cotton. It is: Fabric: 90% Polyester, 10% Spandex Lining: 91% Nylon, 9% Spandex Filling Material: 100% Memory foam

This eye mask offers exceptional comfort and effective light blocking, making it ideal for improving sleep quality. The soft, lightweight material is gentle on the skin and does not irritate sensitive areas, such as ear piercings an issue I’ve experienced with other masks. The adjustable strap allows for a snug, customized fit, and the design effectively eliminates light leakage, including around the nose area where many masks fall short. After using it nightly for several weeks, I’ve experienced quicker sleep onset and more refreshed mornings. Its breathable, padded design remains comfortable throughout the night without causing overheating, although I haven’t tested it in warmer climates. I was impressed enough to purchase a second one as a backup. Highly recommended for anyone seeking a reliable and comfortable sleep mask

Not cotton. Crappy synthetic materials

Have lasted well. Not sure how we managed without them. The inner has special padding so your eyelashes don’t hit the material which is great. Fully black out and adjustable at the back for comfortable fit. Only downside is side is they don’t like being washed as look a bit mis shaped now but it hasn’t really affected the eye part. Just the back strap and that doesn’t really matter.

I have only just received the mask. I tried it on and it certainly keeps out the light. The materials is lovely and soft (I can't tell whether it's cotton or not) and it definitely doesn't put pressure on the eyes. My only issues so far is the following: There was a little packet of "Activated Carbon Deodorizer" with it. The mask has a very strong smell off it. I don't really want to wash it yet and risk losing some of its properties. I'll put it outside on the clothesline and see if the smell disappears... Has anybody else noticed this? This odour would bother me for sleeping.

Terrible. I was specifically seeking out something that wasn't made from petrochemicals and so wouldn't fill my eyeballs with microplastics. This item is advertised as made if cotton. However, it is 90% polyester and 10% spandex. Not even 1%, cotton. This is just a lie. Don't buy. False advertising
