We're not really convinced about this particular travel accessory, but if you need to nap on the move, it might be an idea to invest. This ring pillow fits around your head, essentially blocking off the outside world. will provide just the right amount of padding and light elimination so you don't have to worry about being disturbed by your fellow passengers. Plus it has the added benefit of looking so odd, they'll probably be put off disturbing you anyway. Win-win situation.
