I have easily tried over 20sleep masks from amazon.com amazon.ca and amazon.com.au. This is hands down the best sleep mask for comfort, darkness and durability. I found all those 3d masks only lasted a few weeks where this is still going strong.
Finally, one that fits my face and nose without bothering my skin, "leaking" light by my nose, or pressing on my eyelids. They're not even hot. The face gets to breathe and the light stays OUT. Very comfortable, adjustable strap, and it's not any kind of thick strap that'll bother the back of your head. It's a nice slim design on the strap and Velcro-like fastening. Very nicely made.
I absolutely love the mask. It totally blocks out light. I work at night shift so I really need this mask to get good day time sleep. Will buy again as a spare. I have bought so many masks before and this is the only one that works well.
SOOOOO comfy, i don't even notice them when i sleep almost. i truly sleep better and longer when i wear these. I bought them for a trip (many beach rentals have light curtains) and i slept so well, i wear them every night now and had to order more for my family too.
