Manta Slim Sleep Mask - Ultra-Lightweight Blackout Eye Mask, Slim Comfort Design, Zero Eye Pressure, Infinitely Adjustable Eye Cups, Perfect for Side Sleepers

**Manta SLIM Mask — The world’s best super slim, 100% blackout sleep mask. Guaranteed. The barely-there comfort you want, the 100% light-blocking power you need. 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. *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. Endlessly adjustable strap tightness * 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. *Infinitely adjustable eye cups — 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. *100% Blackout — 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. *Every detail engineered for unmatched comfort — 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.
