The sleep mask that puts you in control. Enjoy total 360-degree blackout for deep sleep, or adjust the front panel to let in light for increased awareness—ideal for napping. WHY IT’S SPECIAL The unique raised foam layer keeps the mask away from your eyes and lashes, so you can blink. Each mask comes with removable contoured eyecups, allowing you to apply (or not) stress-relieving pressure around your eye area. The headband has been made to allow for ultimate ventilation and breathability, thanks to an air-mesh inner panel. The grey outer fabric is 96% bamboo (for comfort) with a hint of spandex (for stretchiness and durability). The black Peek Panel is a blend of rayon, nylon, and spandex.  Every mask comes with a pair of EN352-tested earbuds with a noise reduction rating of 32db.
