- COMFORTABLE: Super-soft sleep mask worthy of a nap ninja
- KOALA DESIGN: This plush mask is designed to emulate Kage the NAPJITSU koala because koalas are professional sleepers, logging 18-22 hours a day
- THE SCIENCE: Your body is sensitive to light, and we have 24-hour sleep-wake cycles. That cycle — a circadian rhythm — helps you sleep at night and be wakeful during the day. A sleep mask helps to block out the light that can trigger wakefulness, whether it’s afternoon sunshine or an early sunrise. Less light means more snoozing, because you need good rest to awaken your inner ninja.
