Are you looking for a customized fit for your comfort? Introducing Evolution S3 by Cabeau, the world’s best engineered neck pillow. Our innovative Seat Strap System eliminates head drop, neck strain, and the instinctive "whiplash" response to reopen obstructed airways. Wrap the straps around the headrest area of your plane seat, gaming chair, or theater seat to secure your head in place. The premium memory foam core and raised side supports cradle your head and neck to prevent lateral movement and stop you from waking up on your seat mate's shoulder. Our Evolution S3 pillow compacts to half its size in our included compact case that attaches to backpacks or carry-ons for critical space saving whether you're traveling on an airplane or in the car.
