Great for naps, but always room for improvement!
I've brought this to my campus several times. I can nap on one of our library couches and I feel much better when waking up, too. It's great for blocking out light and serves as a comfy pillow. As far as noise-canceling, though, it's not terribly effective. For instance, if I was trying to sleep through a thunderstorm, I would still hear it cracking loudly with little protection. If a variant came out with built-in earmuffs, for instance, I think it would be perfect!
