how it works

soothe & depuff your eyes — so you look (and feel) well-rested, everyday

COOL Mask is tailor-made for those looking to relax and rejuvenate their eyes — so they can feel refreshed and ready for the day instantly.

A cooling eye mask calms & relaxes you by reducing inflammation in the blood vessels around your eyes and invigorating your delicate eye skin — so you look (and feel) well-rested, within minutes.

The result: you're never slowed down by allergies or tired eyes — and you never feel puffy for longer than a few minutes.

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

what makes this cooling eye mask different

for the perfect blend of comfort and relief

COOL offers compression everywhere you need it (and nowhere you don’t). With this cooling eye mask, you get therapeutic pressure around your eyes and on your sinuses, but little pressure on your eyes — so you feel instant, soothing relief.

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

for relief that protects your delicate eye skin

COOL is filled with cooling beads that are gentler than gel and insulated to stay frozen 20% longer than other bead masks. They’re ice cold for the doctor-recommended duration of 10 minutes: long enough to provide relief, but brief enough to prevent skin damage.
"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!"

for right-where-you-need-it cold therapy

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 instant, sigh-worthy relief.

"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."

so you get darkness & cooling, at the same time

Designed to give you an immersive cooling experience, COOL’s eye cups are large and wide enough to block out 100% of light for most people. The result: you get total sensory relief, every time — and you recover quickly from headaches that are exacerbated by light.

"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!"

for unmatched comfort, in any position

COOL is designed for no-compromises comfort and constructed with soft, breathable, moldable materials that gently conform to your face while putting minimal pressure on your eyes. So you experience immediate relief 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."

How do I use Manta COOL Mask?

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.
