Snug fit, soft to the touch. Ive been looking for a good sleep mask for awhile, when i accidentally stumbled on this one. It was not a popular (main) brand, but, what gravitated me was the band. Premium quality material, sits comfortably on my face, soft texture feel nice, blocks out 100% light, cups around the eye, and biggest thing would be how the band does not go over my ear. It stays on all night :)

I love this sleep mask. Ive tried many over the years, most recently several versions of the manta sleep. The SideSleeperZ stays in place all night. It leaves room for my eyelashes, while still not obtruding against the pillow on the side of the head. Pitch black with no light leaking through. And the piece against the nose can be pushed upward while still blocking the light so that nasal passages do not overheat and stuff up as they did on other masks. Well worth the price.

I’ll be honest I switched from using the Manta mask and I didn’t think this one would be better but it actually is!! The straps being above and below your ears help so much for security during the night and comfortability. 100% darkness as well, absolutely zero light shining through. Definitely give this mask a try!
Tj 5/5 Verified
I have tried them all … this mask is absolutely the best! Completely blocks all light. There is no light infiltration from the bottom of the mask. I’ll be ordering another for travel. Five stars!

Best mask ever.

first sleep mask to stay on throughout the night
Logan 5/5 Verified
My wife and I love our Sidesleeperz. Our sleep quality has noticeably improved. For starters, we no longer get woken up in the middle of the night by our rear neighbor's back porch light which illuminates the room with the intensity of a thousand suns. We are also able to sleep later into the early morning as the masks keep the dawn light at bay.

It’s really great it stays on my head all night, total blackout, and extremely comfortable. I’m the type to get really warm and no complaints.
Jonmarc 5/5 Verified
Fits great and I'm a petite woman, it's very adjustable. Comfortable to wear and offers completely darkness. I'm very happy in my sidesleeper mask !
Dru Lucia 5/5 Verified
I was hesitant to spend the money, but I'm happy with the mask. I've only used super cheap ones in the past. It is an awesome upgrade.
Beau 5/5 Verified
The double adjustable straps help this mask achieve the best darkness I've gotten from a mask.

Best mask ever. Stays put all night and comfortable. Bought one for wife also.
Jayme 5/5 Verified
used this for a few days now. it's AMAZING! I have never used a sleep mask before that really do blocks out any light, comfortable, and still stayed on after hours of sleep and waking up. this is definitely a good buy for me.

Loving it!
Cameron 5/5 Verified
I cannot be happier with this purchase. This is the only mask that has not came off of my head that I've purchased so far. I spent over $100 on the last one and it still didn't work out. Very impressed!
Jeremy 5/5 Verified
Recently started using sleeping masks but hated how I could never keep one on my face because I rotate like a rotisserie chicken in my sleep. Love how this stays in place all night!
Jason 5/5 Verified
This is the first mask that does not just fly right off my head when I'm side sleeping. The name of the product is fitting and I cannot be happier.
Jeremy 5/5 Verified
Took a few nights to get used to it, but now I sleep like the dead
Ethan 5/5 Verified
I shopped around for a while for a mask that looked like it had what I needed. My main annoyance with sleep masks is the strap and buckle digging into my ear and temple when sleeping on my side. This mask solved all of that and more. It's feels quality. It completely blocks out light, it's adjustable, and so comfortable that I'm no longer walking up in the middle of the night fixing it. It also helps keeps my eyes from drying out as much from my bedside fan, which is an added bonus. It's a little expensive when compared to other sleep masks, but it's something I use every night and rely on, so it's well worth the money to me.
Dillon 5/5 Verified
I just wore this thing for 46 hours straight as part of a darkness meditation retreat. It worked perfectly and was genuinely comfortable the whole time. It only came off once, when I was doing deep neck stretches, so that's my own fault! Recommend very highly.
E 5/5 Verified
Very comfortable and remains in place all night unlike other sleep masks I have tried previously. It is clear to see from the design and the quality of the materials that this is a very good product for side sleepers and one that will continue to reward me through consistent and improved sleep - thank you!
Jamie 5/5 Verified
Great product, nice quality, worth every penny! Best sleeping mask on the market
Francisco 5/5 Verified
Extremely comfortable and love the gap between the eyes and mask!
Kyle 5/5 Verified
Best sleep mask in the market! Have not encountered it fall off my face yet! Highly recommend for side sleepers such as myself.
Timothy 5/5 Verified
I seem to be getting more deep sleep since I started wearing it. Thank you.
Pascal 5/5 Verified
The sleep mask is surprisingly comfortable, and is the most adjustable sleep mask I have used. I can use it in the middle of the day in a room that isn't darkened, and it is like being in a pitch black room. It is very comfortable on the eyes. It is easy to adjust without even looking at the straps. The carrying bag and the laundry mesh bag are very helpful.
Robert 5/5 Verified
I've bought around 4 different sleeping masks, ranging from cheap ones to expensive ones and this is the only sleeping mask that actually stayed in my face for the whole night despite twisting and turning. Highly recommend!
Ray Aerold 5/5 Verified
I’ve been using the sleep mask nightly for about a week. I appreciate how adjustable and comfortable it is. I haven’t had any issues with light leaking or the straps rubbing on my ears. Overall it’s one of the better sleep masks I’ve used.
Sam 5/5 Verified
super comfortable and first sleep mask that actually stays on overnight
Felix 5/5 Verified
Great product
Dave 5/5 Verified
Very happy with it! This is the only mask i've found that completely keeps out the light when I lie on my side. I have the Manta Pro mask, and while it is a great mask, it's not as comfortable or as light-proof as the SideSleeperZ. The reduced pressure on my head when using this mask is especially noticeable, and I find I sleep better on my side with it than any other mask I've tried.
