It might take a minute to get this properly adjusted to your comfort but once you do, it's pretty great. I'm a big fan of sleep masks in general but this one is especially nice, with the added cushioning for your head and the straps to secure it to a headrest. The fabric is soft, the 3d mask is nice and plush and it blocks out every bit of light. Sometimes the flat masks can let in a little light from the bottom, where your nose goes, but this one is not messing around. It's 100% lights out.I can see this being great not just for flying but also if you're the passenger on a long road trip, or even a bus/train excursion. I will warn that if you're prone to claustrophobia it might be a bit much, especially at first. But if that's not an issue for you, this is a great item for traveling.
