This is the first sleep mask that stays on my face through the night more than 60% of the time. It’s not 100% but I am extremely happy with it. Very comfy, very adjustable. Love it!

I am very impressed about the blackout effect of this Mask (no light scape at all), and secondly it is genuinely comfortable to use, it doesn't damage your ear's sides as all of them do. Then, I love the fact that it stays on all night! However I would say that if you sleep with a very rough cotton texture pillow case then it might move a tiny bit, but otherwise it ll stay on in most cases especially if you sleep with a silk texture like pillow case. Overall, it is the best sleeping gadget I bought in a long time, well done SideSleeper!
Nour 5/5 Verified
Very pleased with this product. Pretty much as advertised, doesn't come off. It's perfectly dark and incredibly comfortable. Well done!
Don 5/5 Verified
Extremely comfortable, complete blackout, and hasn't shifted once when sleeping. Exactly what I was looking for.

Great mask, finally one that doesn't feel like it's trying to cut my ears off from the top

Fantastic. Couldn’t do sleep masks. Can do this one.
Justin 5/5 Verified
I am enjoying it! Upgraded from my old sleep mask & don’t see any light when I’m wearing it and can sleep on my side without it moving. Really cool design.
Lacey 5/5 Verified
Amazing sleep mask. Complete darkness. Im a side sleeper and I have never had such a comfortable sleep mask. Does not move, easy to adjust, I love the purchase!
Raymond 5/5 Verified

Fits well and doesn’t hurt my ears.
William 5/5 Verified
The best, most comfortable eye mask. I dont even notice it while im sleeping and it totally blocks out any light.
Mark 5/5 Verified
Fits well. Don't even notice it, while falling asleep. Doesn't seem to bother me, if I wake up in the middle of the night. It stays put.
John 5/5 Verified
Only mask that stays on while I sleep and is comfortable.
Matt 5/5 Verified
Sleep mask stays on the entire night and blocks all of the light that normally gets past other sleep masks.
Michael 5/5 Verified

Uel 5/5 Verified
Finally - a sleep mask that blocks out all of the light, BUT DOESNT SLIP OFF OF MY HEAD! Best purchase ever. I’m immediately getting a backup.
Kim 5/5 Verified
The mask is very comfortable.
Geoffrey 5/5 Verified
Best mask ever
Robert 5/5 Verified
Best sleep mask I’ve ever used. Total blackout. No pressure on my eyes or nose. Not hot. Completely stays in place and I move around a lot! This will be at the top of my list to gift friends and family this year. Great design!
Karen 5/5 Verified
Amazing. Doesn’t come off.
Jacob 5/5 Verified
The best eye mask ive ever used and i probably have tried 20 different ones
Jacob 5/5 Verified
Truly life-changing sleep mask if you work nightshifts. I have used a generic sleep mask for years and it has never once been over my eyes when I woke up. The SideSleeperZ stays covering my eyes every single night. It's a cheaper price than other premium sleep masks with great quality. Would highly recommend.
Andrew 5/5 Verified
Able to completely block out light and not falling off after a night of sleep. Finally able to sleep through the early morning!
Fang 5/5 Verified
Absolutely love it! I have been more energized and feel like I’m ready to wake up since using it. It’s been a rough week as far as time available for sleep but with this, I wake up feeling refreshed even on 5 hours sleep the past week.
Hogan 5/5 Verified
Very comfortable, stays in place without any movement. Complete coverage with no light seeping in. The design around the ears is sleep mask perfection!!! A 10 out of 10. This is my sleep mask forever!! Thanks Sidesleeper Z.
Mark 5/5 Verified
my third pair so far, very comfy!
Caylin 5/5 Verified
This mask is great. Way better than the Manta mask. I will order another if they release a taupe or tan one
Rob 5/5 Verified
I really love that it molds to my face and that it has adjustable straps that are very secure. I don't have to deal with the mask coming off in the middle of the night, even as a side-sleeper.
Ringo 5/5 Verified
I'm an airline pilot and I have to sleep at all hours of the day. Blackout curtains weren't enough and i got used to this immediately. Buying my second one today so i have one in my flight bag and one at home
Brian 5/5 Verified
It's very comfortable. I appreciate the dual head straps that avoid the ears. My only critique would be that the lower strap is too short and thick. I'm only able to engage the Velcro with about 10mm of overlap. Additionally, the Velcro creates a pressure point on the back of your head when laying on the pillow. The thin upper elastic strap is great. I would prefer that being used in both positions.
August 5/5 Verified
This mask actually stays put on my face, and really doesn’t let any light through in the morning, letting me sleep in, which is a small miracle!
Leslie 5/5 Verified
Great mask for side sleepers!! I was hesitant but after reading reviews I bit the bullet and love it!! I can’t stand the feeling of straps too tight or if I can feel the bands along my head while laying down and this mask is so adjustable that I always find a comfortable position for it. Highly recommend!
Jake 5/5 Verified
I am someone that tosses and turns quite a bit and this thing ain't goin nowhere! It doesn't even have to be on too snug to stay in place. And provides full blackout no matter what time of day. Absolutely love it!
Alana 5/5 Verified
This is complete blackout, but more importantly, to me at least, it isnt budging or slipping off my head in the night! I love it! (I’ve probably got at least 20 other different sleep masks here that I’ve tried and been disappointed by, so this is major for me)
Kim 5/5 Verified
THE best I've ever used. PERFECT actually. Perfect blackout. Perfect on eliminating pressure on the ears and eyes. Perfect on staying in place all night. This is waaaaaay better than the Tempurpedic mask!!!
