Have you ever reclined in an airplane seat and snuggled in for a snooze only to feel your head start to tingle as you wonder who sat there before you? Then, you realize that many commercial airlines only clean their planes every 3-4 weeks.
For a better and germ-free experience, think about getting a Head Defender to keep your head clean on planes. They are lightweight, machine-washable, anti-microbial, hypo-allergenic seat covers that are simple to use. You just slip one over an airplane seat (they fit most standard airline seats). Head Defenders can also be used on trains. They come in a variety of covers and start at $14.99.
