Introducing the ultimate solution to uncomfortable travel: The Necks Evolution S3. This revolutionary travel pillow features latest innovation: the comfiest, most secure, gravity defying chin-strap technology that allows for maximum head and neck support at all angles, while cleverly leaving a large opening at the front of the neck for heat to escape. Your head falling forward while trying to sleep on a plane is now a thing of the past! The Necks Evolution S3 also includes our revolutionary raised side supports and seat strap system that keeps your head in place as you drift off to sleep and stay that way - on flights and on all high-back seats.
