These feature C-shaped eye cups that are thinly tapered at the temples — so there’s practically no material between your head and the pillow as you lie on your side.

In addition to that, the eye cups feature a smart “air bubble” that expands to keep light out when switching positions, and compresses flat when you lie on your side, to give you a perfect blackout seal with none of the bulk.

Yes, 100% machine washable. To wash the mask, use cold water and put the mask (with the eye cups) in the included carrying pouch, which doubles as a laundry mesh net, and put it in the washer. Once you’re done washing, air dry the mask by laying it flat.

Sleep Mask PRO is perfect for traveling. It gives you 100% blackout even in broad daylight. It doesn’t put any pressure directly on the eyes, so you won’t get blurry vision when you take it off. Also, the strap tightness is infinitely adjustable, so it fits perfectly.

We design our masks to fit every face type perfectly. Its spacious, C-shaped eye cups are tapered at the edges — and they can be placed anywhere along the head strap for a flawless blackout fit.
