My wife’s loving being able to sleep through the movie theater and late night gaming taking place while She knocks out on the lovesac
Complete black out. Comfortable. Worth the buy
It’s great
Loving it!
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!
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!
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.
Took a few nights to get used to it, but now I sleep like the dead
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.
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.
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!
Great product, nice quality, worth every penny! Best sleeping mask on the market
Extremely comfortable and love the gap between the eyes and mask!
Best sleep mask in the market! Have not encountered it fall off my face yet! Highly recommend for side sleepers such as myself.
I seem to be getting more deep sleep since I started wearing it. Thank you.
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.
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!
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.
super comfortable and first sleep mask that actually stays on overnight
Great product
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.
Best mask I have had…comfortable and very dark
I use this product almost every night as a Green Apron Barista who normally works the morning shift. It has been a game changer in my sleep. I truly enjoy using them!
I’m extremely sensitive to light when I sleep, and even the smallest amount can wake me up. I’ve tried several sleep masks, but they all seemed to let in some light depending on my sleeping position. Another issue I’ve always had is my eyelashes touching the inside of the eye cups, which I find really uncomfortable. I was skeptical about this mask at first and assumed it might be another gimmick, but the positive reviews convinced me to give it a try. I’m glad I did. It has been exactly what I was looking for. As a side sleeper, this mask is incredibly comfortable. It blocks out light completely, keeps the eye cups away from my eyes and eyelashes, and stays comfortable throughout the night. If you’re looking for a sleep mask that actually delivers on its promises, I highly recommend giving this one a try.
This sleep mask is wonderful! It fixes all the issues I've had with prior sleep masks. The straps completely avoid the ears. It creates a complete blackout. It stays in place all night (no sliding around your head). It's comfortable. And most unusual for me, the straps are customizable enough that it fits my head (I'm small for an adult). I'll be ordering back ups for sure!
Best mask so far on the market.
Very comfortable all around especially with the split head band. My single headband eye mask would regularly press down on my ears and hurt pretty bad after a few hours of sleep. This mask is also nearly impossible to slip off during use. Very satisfied!
Easy to wear! Easy to wash! Love it! Need a back up.
Good.
Hands down the best sleep mask out there.
I've tried a LOT of sleep masks, attempting to find one that not only fits my face comfortably but also stays on and doesn't slip during the night. Without question, the Sidesleeperz mask is THE BEST SLEEP MASK I'VE EVER BOUGHT! The ingenious way it's designed -- with two straps and the top strap being fully adjustable to each person's face and comfort level -- works smashingly. Not only does it fit perfectly, but it also blocks the light completely. What more could you ask for? Really, I'm happy to leave an enthusiastic review because I am so enthusiastic about this product.
The best side sleep mask
I have been trying to find the perfect sleep mask for almost ten whole years now...and with this one, I can finally mark my search complete. This design and light seal completely blows the other, sometimes more expensive, options out of the water. It's lighter, less pressure on the face, more comfortable to sleep in, and overall a better value for the money. Listen, I am the pickiest dude you'll ever meet, especially when it comes to tactile sensations, fit, and anything that TOUCHES YOUR FACE while you're supposed to be asleep. This sleep mask was one of those very rare exceptions where I have no notes, no nitpicks...literally nothing but positive feelings. This is a 10/10 purchase for me. I haven't bought anything in a long time that has impressed me as much as this.
Love this mask so much. Tried the manta pro before this and it really irritated my ears and had a tiny but of light peaking through. I am a night shift RN so my sleep means a lot to me. The sidesleeperz is next level. Unfortunately I lost it on a trip just 2 weeks after having it and my sleep has not been good since. Ordering a new one and it is well worth it. Even though my room is fully blackout, I use this mask on my nights off, it is almost like the comfiest weighted blanket for my face (its not heavy, its just so comfy and secure). Can’t suggest this product enough! It is fully adjustable, and fully blackout. The mask is incredibly soft so it will not irritate your fave when trying to sleep.
Best sleep mask I have ever worn. Highly recommended!!!
Best sleep mask I have owned for sure. Stays on as is super comfortable. Definitely not cheap but my rule is anything sleep related I spare no expense. They also shipped me an additional strap. Very classy move guys!
Works great, very comfortable!
Finally a mask that blocks all the light(100%) allowing for that extra hour of recovery sleep. I don't feel my eyelashes rubbing up against the interior portion of the mask. Stays in place throughout the entire night. Minimal pressure. Very plush comfortable material against the face. Built with the intention to last many years. A+++ 10/10 star rating from my personal experience, paid for by me. Highly recommend.
Love my new sleep mask! I sleep like a baby now!
