When you travel long distances, your body is forced to stay in a fixed position for extended periods. If you aren't comfortable during the car, plane, or train ride, what should've been an enjoyable holiday can easily turn into a literal pain in the neck. The last thing you'll want is to prepare and spend for the vacation only to arrive at your destination all cramped and sore. This is the reason a travel pillow is a must-have for frequent and casual travelers alike.
