Many U-shaped foam neck rests are often cumbersome. Muji offers a micro-bead version, which is understated in shape and can lie flat or mold around your head and neck. Its utility has options for lumbar and side support or face-down sleeping. And it can be squashed in your carryon without destroying it. It is available in several colors and the cover is removable and washable.
