Just a pinprick of light can disrupt REM and deep sleep, leading to post-sleep tiredness. That’s why the Hibernate Sleep Mask perfectly covers and conforms to your eyes to block 100% of light, even in broad daylight — so you always get deep, uninterrupted sleep.
Infinitely adjustable comfort straps for a perfect, personalized-for-your-face fit.
The Hibernate Sleep Mask is made to fit your unique face. Your eye pads’ 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.)
