Head strap adjusts easily, and it keeps out 100% of light for me. I find it comfortable to wear and use it at night. I would recommend this sleep mask.

The mask is cool! Completely blocks light, 100% black out. Sewn perfectly. Synthetic material. A must-have for long flights! If you sleep at home on your side or stomach, you need to get used to it.

Third time I order them. This is a wonderful gift.
This is the best eye mask I have found and searched for completely.
Both at airports, both in online stores, and also in regular stores.
Recommend!! !

Honestly, I've never used an eye mask before, so I wanted to try it out. At first impression, I really like it. It completely blocks out light and I feel like that will help me sleep better. It's comfortable, although I feel like you need to get used to the feeling of wearing it.
D
Great product. Blocks out light completely.

This truly is the best sleep mask i ever owned, because all masks are so cheap on ali i bought 5 different ones, and i've tried them all but this one is the only one that makes it pitch black, also near your nose where usually light finds a way trough, the material is very soft so the elastic strap doesn't hurt your ears or head when the night progresses.
I am a bad sleeper and i wake up from everything, rain drops, squeaks or wood cracks or the blinds outside, so i wear custom ear plugs, but i also wake up from the light, but this mask is so good, i am thinking about ordering a box so i have them for the rest of my life.
This is my honest opinion, i truly like this mask.
Buy it yourself and see what i mean, in the worst case you lose 7 bucks.
In the best case you sleep just as good as i do now :)

K
cool. fits well, doesn't squeeze, doesn't let any light through
F
Quite comfortable and easy to ajust. Due to the nose strap it helps block all of the light
A
The second one i bought. Totally blocks all light.
E
These are decent quality, and the space for the eyes is large enough that you can pretty much open your eyes with the mask on. No pressure on the eyes while the mask is on which is great and comfortable. Blocks out all light - the nose covering portion blocks out any cracks of light. Will order again!
S
Comfy and blocks light effectively
L
Doesn't hurt the eyes, doesn't let light through. Everything is great!

The best sleep mask there is on the market. Order this to vary in color and have several in stock.
A few things you might want to know.
How do I know whether the fit is right?
Check the measurements and product details before ordering. The fit should feel comfortable. If it causes discomfort, numbness or tingling, remove it. Contact our team if you need help choosing.
How long should I wear it, and how do I clean it?
Use the wear time and cleaning method in the instructions supplied with your product. Preparation and care differ between items, so do not use another product’s instructions.
How do I choose the right product?
Choose by the area you want to cover. The cap wraps around the head, the sleep mask covers the eyes, and each joint sleeve is shaped for its named body area. Bundles combine complementary products.
How do I prepare my product?
Follow the instructions supplied with your specific product for preparation, temperature and wear time. Check the temperature before use and stop if it feels uncomfortable. Do not assume every gel product can be heated.
