meet the world’s best barely-there sleep mask

SLIM is the only slimline mask designed, constructed and optimized for deepest-possible sleep in any environment.

Created to channel the sleep-boosting power of 100% blackout into the slimmest-possible mask, SLIM is for you whether you’re a side sleeper with sensitive ears or you simply prefer a barely-there mask.

Because better sleep means better everything.









what it's for

features a narrow above-the-ear strap and streamlined materials for a sleek, barely-there feel

SLIM Mask is tailor-made for minimalists and side sleepers with sensitive ears.

Some sleepers sleep best when they can hardly feel their mask on their head. That’s why SLIM is trimmed down, streamlined and optimized for leanness — without sacrificing comfiness.

The result: SLIM is barely perceptible on your head or against your ears — so you sleep deeply, even if your ears are super sensitive and you always sleep on your side.

"I got my slim mask a few weeks ago and love it! Great fit, comfy and light blocking 👌🏻 "


what makes slim different

anti-stretch elastics for best-in-class durability

SLIM's strap is constructed with the same elastics used in top-quality ski masks — not cheap airline sleep masks. It's reinforced with soft polyester that preserves and protects the stretchy fibers that normally wear out — so your strap stays stretchier, longer.

"This mask is incredibly soft, light, and blocks almost all light. It’s perfect for midday naps to kill a headache or to help me get back to sleep when I wake up in the early hours of the morning."


endlessly adjustable strap tightness for optimal fit

SLIM will always fit like the first time you wore it — no matter how long you've had it. Most elastic straps become unusable as they loosen over time — but SLIM's strap is 100% coated in soft micro fleece and micro hooks, so it's endlessly adjustable and will fit perfectly forever.

"They fixed all the issues I've ever had with eye masks (and I have tried them all!) and then some! I was hesitant to spend $30ish on an eye mask but knowing what I know now I wouldn't even hesitate."


infinitely adjustable eye cups for a perfect, personalized-for-your-face fit

SLIM is made to fit your unique face. Your eye cups’ position, angle and strap tightness are infinitely adjustable for a fit so seamless, you barely feel your mask on your face. It's like it was custom made for you. (Because it basically was.)

"It is truly the ONLY mask I have found that is truly 100% blackout. I tried it and the very next morning I woke up and threw 4 other masks I had purchased right in the garbage."


100% blackout for maximized sleep quality — so you feel 100%, all the time

Just a pinprick of light can disrupt REM and deep sleep, leading to post-sleep tiredness. That’s why SLIM perfectly covers and conforms to your eyes to block 100% of light, even in broad daylight — so you always get deep, uninterrupted sleep.

"Think of these masks as the BMW of masks. Sure, you can find cheaper options, but if you want the best, you'll pay a little more."


every detail engineered for unmatched comfort, in any position

SLIM Mask is designed for no-compromises comfort and constructed with soft, durable, snag-free materials that gently conform to your face without putting any pressure on your eyes. So you sleep as well as humanly possible whether you’re on your back, side or stomach.

"I've never been able to sleep with a mask on because I find it uncomfortable, but the Manta slim mask is super soft and doesn't put pressure on my eyes. Highly recommend!"

What is the difference between the Manta SLIM Mask and the Original Manta SLEEP Mask?

Good question! Both masks use the same eye cups which are tapered on the sides to ensure your comfort regardless of your sleep position. The only difference is in the head straps. The Manta SLIM Mask uses an above-the-ear strap that’s mostly made from durable, anti-stretch elastics so it’s perfect if you want a sleek, barely-there feel.

On the other hand, the Original Manta SLEEP Mask uses a strap that’s mostly made from cotton polyester. It has triple-reinforced elastics on both sides, but since the strap isn't pure elastics, it can be worn above and over the ears.

Is it comfortable for back sleepers? Side sleepers? Belly sleepers?

For back sleepers: the head strap is mostly made with anti-stretch elastics so you’ll forget it’s even there.

For side sleepers and belly sleepers: The product was designed with you in mind. Because most people don’t sleep flat on their back, the Manta SLIM Mask’s eye cups are tapered on the side for extra comfort. The foam is also soft and molds to your face.

If you’ve only used the cheap and flat airline sleep masks, it may take a day or two to adjust to Manta’s design. However, we have hundreds of thousands of happy customers and most find the product to be comfortable regardless of sleeping position.

How do I clean my Manta SLIM Mask?

The Manta SLIM Mask could both be hand and machine washed cold. For machine washing though, we recommend using a small laundry / mesh bag to protect the mask from getting damaged. Please don’t use bleach. Once you’re done washing the mask, please air dry flat.

Would this work with a CPAP mask?

We have tons of customers who use our Manta SLIM Mask with their CPAP mask. However, since there are lots of different models of CPAP machines in the market, it’s hard to say for sure that our mask would work with every model. The eye cups and the strap of the Manta SLIM Mask are highly customizable though so chances are they’ll work well with your CPAP mask. Please check out the photos of the Manta SLIM Mask and compare them with your CPAP machine for reference.
