how it works

ALL IT TAKES IS 10 MINUTES TO
refresh your eyes — so you feel naturally rested, every day

COOL Mask is tailor-made for those looking to relax and refresh their eyes — helping you unwind and feel recharged in just a few minutes.

A cooling eye mask calms and relaxes you with gentle coolness and a comforting feel — so you look (and feel) naturally refreshed within minutes.

The result: a soothing sensation that promotes comfort and helps you feel calm and refreshed.

"It completely blocks out the light and relieves the tension headaches I get from staring at a computer all day."

Heatherly

what makes this cooling sleep mask different

GENTLE, PRESSURE-FREE COMPRESSION
for the perfect blend of comfort and relaxation

COOL offers gentle pressure everywhere you need it (and nowhere you don’t). With this cooling eye mask, you get soothing pressure around your eyes, with minimal pressure directly on them — so you feel calming, refreshing comfort.

"I suffer from awful sinus headaches and allergies and the cooling mask is seriously the best money I have spent all year!"

Amanda

THE PERFECT AMOUNT OF COOLNESS
to refresh the delicate skin around your eyes

COOL is filled with cooling beads that provide a gentle, cooling sensation and are insulated to stay cold longer than typical bead masks. They stay cool for around 10 minutes: long enough to offer a refreshing sensation while being safe for your skin.

"I usually have terrible allergies and my sinuses are always angry and swollen. When I woke up this morning, my sinuses felt so much better!"

Kelsy

100% ADJUSTABLE FIT
for cooling comfort right where you need it

COOL is made to fit your unique face. Its eye cups’ position, angle and strap tightness are infinitely adjustable — so you can position your ice-cold eye cups exactly where you need them for a soothing experience.

"After just two uses, there is significant improvement: the bruising has faded; my eyes aren’t itching; and I don’t cringe when I look in the mirror."

Sherri

NEAR-BLACKOUT DESIGN
so you get darkness & cooling, at the same time

Designed for an immersive cooling experience, COOL’s eye cups are large and wide enough to block the majority of light for most people. The result: a soothing, sensory experience that helps you relax in bright environments.

"I bought these in hopes that they would maybe help the puffiness and boy they did! It feels nice to sit back and just chill (pun intended) while my eyes depuff in the morning and then I am ready to take on the day!"

Amy

EVERY DETAIL ENGINEERED
for unmatched comfort, in any position

COOL is designed for comfort and constructed with soft, breathable, mouldable materials that gently conform to your face while putting minimal pressure on your eyes. So you experience comfort whether you’re on your back, side or stomach.

"The temperature is perfect - not too cold to hurt - and it relieves the pressure from my eyes while providing complete black-out darkness which is very helpful for migraines."

Better than a lot but still some issues
Probably one of the better 100% blackout sleep mask because of the eye cups/retaining strap design however the strap can irritate the ear lobes

Thank you for taking the time to share your thoughts about the Manta COOL Sleep Mask, Curt.

We truly appreciate your honest review and while we're pleased to hear that you find our mask's blackout capabilities and eye cup design effective, we understand your concerns about the strap causing ear lobe discomfort. While we strive to create sleep solutions that combine complete darkness with optimal comfort, we recognize that the current strap design hasn't provided the comfort level you were hoping for.

Your specific feedback about the strap's interaction with your ear lobes is particularly valuable to us. Although we've engineered our strap system to maintain a secure fit throughout the night, we understand that this shouldn't come at the expense of comfort - this isn't the experience we aim for with our products.

These insights about the strap design are especially helpful for our product development team as we continue to work on improvements to better serve our customers' sleep needs. Thank you again for sharing your candid perspective.

Great for relaxing the eyes !
Great product. While I don’t use it for sleeping I do use it to relax my eyes prior to going to bed for 20 minutes and it works wonders. The cold does last about 15-20 minutes so don’t expect it to last overnight at all. However I still recommend the purchase !

Great!
I bought this to help my teenage son sleep at night. Every morning he's putting his eye patches in the freezer, and every night he gets them back out, so I know he isn't trying to protect my feelings when he tells me that it works great.

That sounds like the ultimate endorsement! 😄 If your son’s out here freezing the patches every night, you know it’s gotta be working wonders. Love that it’s helping him get the sleep he needs! 💙

faq

How do I use Manta COOL Mask?

Place the detachable eye cups from Manta COOL Mask in the ziplock bag that comes in the package. Place the bag in the freezer at least 1 hour prior to usage. Once cooled, place the eye cups on the head strap and put the mask on for immediate head, eye and sinus relief.

How long does the cooling effect from Manta COOL Mask last?

If cooled in the freezer according to the instructions given, COOL eye cups remain ice cold for the doctor-recommended duration of 10 minutes, which is long enough to soothe your head, eyes and sinuses without damaging your skin.

How do I know that Manta COOL Mask will fit me?

Manta COOL Mask is designed to fit every face type perfectly. Its detachable eye cups can be placed anywhere along the head strap for a flawless blackout fit.

The head strap itself is 73 cm in circumference, and is fully adjustable to ensure that it fits perfectly but is never too tight.

Does Manta COOL Mask provide full blackout?

The eye cups on Manta COOL Mask are large and wide enough to block 100% of light for most people. This way, you get complete sensory relief — both because of the cooling effect and complete darkness.

Do you have any other mask options? How do I know which one is best for me?

We make masks for every sleep type and challenge. To find the Manta Mask that’s perfect for you, visit our mask comparison page.

Is Manta COOL Mask machine washable?

Manta COOL Mask should be hand washed only. Please do not machine wash the mask as it may get damaged.

I’m a side sleeper. Is Manta COOL Mask suitable for me?

Manta COOL Mask is filled with cooling beads that soothe your head, eyes and sinuses while you sleep. Because of this, COOL is most comfortable for back sleepers.

If you’re looking for the ultimate mask for side sleepers, check out Manta PRO Sleep Mask.
