Frequently asked questions

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.

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.

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.

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.

COOL Eye Cups are designed to be cooled only. Please do not heat or microwave COOL Eye Cups. If you're looking for a mask that provides steamy heat, check out Manta STEAM Mask.

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

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

The Manta COOL Eye Cups contain special ceramic beads which may get damaged in the washing machine so we only recommend gentle hand washing for these. Please air dry flat the full mask once you’re done washing it.

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.

    comfortable and relaxing

    This is my first experience with Manta Sleep, referred by a friend. The cooling 'pods' cool and are comfortable to wear for the limit suggested time for longer the cooling subsides. I use it to relax my eyes after riding for long miles cycling or after a long day of working with information on computer screens. Since having surgery on my right eye, to correct my vision after a bicycling accident (eye muscle dissection) the Cooling Sleep mask helps to relax and relive the tiredness from daily eye use,

    Hi. It’s wonderful to hear that your friend recommended us and that the Cool Mask is providing the relief you need after cycling and surgery recovery! We’re honored to be a part of your post-ride relaxation and eye care routine.

    To get even more out of those cooling sessions, some of our users keep an extra set of cooling pods in the freezer so they can swap them out for extended relief. We appreciate you sharing your story and your support for Manta Sleep.

    If you ever need assistance or have questions, our Customer Success Team is always here to help.

    In love 😻

    Simply the best eye mask ever! As a frequent traveller there’s nothing better for on the plane than this Manta eye mask. Easy to maintain and fits easily in my carryon bag.

    I am just devastated that I left mine behind during my last work trip. Is there a Black Friday sale coming up?
