So this will be great for most of you. I loved this band even though the strap was not super helpful because I am very tall. I was not able to keep it tight on the seat's headrest.

Super comfortable, shuts out the people around you. Where I could brace it, it works very well to keep your head still and you can lean to the side easily and remain stable. WAY BETTER than the turtle-neck-brace types. I traveled 50+ hours on planes with both.
