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 slender elastic band 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.*Ultimate 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 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.
