Evolution S3 - the best-constructed neck pillow in the world. The innovative Seat Strap System prevents your head from falling, reduces neck strain, and mitigates the instinctive "whiplash" reaction to open blocked airways. Wrap the straps around the headrest of your airplane seat, gaming chair, or cinema seat to secure your head. The elevated side supports prevent lateral movement and stop you from drooling on your neighbor's shoulder. The thin, flat backrest ensures perfect spinal alignment, relaxes your back, and alleviates tension that can overwhelm the neck and shoulder muscles. An adjustable closure at the front provides personalized comfort. The high-quality memory foam core is protected by a moisture-wicking, machine-washable cover that keeps your neck dry and looking fresh. The pillow can be reduced to half its size in the included bag, which can be conveniently attached to backpacks or carry-on luggage.
