so it doesnt strangle you like a turtle neck or other type of wrap
full disclosure: you look goofy. but it helps with the head bob when you doze off on the plane. there is a stiff bump out around your voice box, so it doesnt strangle you like a turtle neck or other type of wrap. this is more like a cervical collar. i left mine in a hotel room, so i had to repurchase! happily!
