A good night's sleep is already hard to come by, so the last thing you need is distracting lights to keep you up when you finally find time to hit the hay. Whether you have inconsiderate roommates or an array of electronic devices that shine in your room, the Manta Sleep Mask v2 helps you sleep anytime and anywhere in 100% darkness. It's fully customizable for the perfect fit, and it contours to your eyes, applying zero pressure and allowing for REM sleep. Plus, with the included blackout stickers, you can completely block out bright lights on your electronics, like power strips and chargers, without leaving a sticky residue.
