Practical because you can remove the "cushion" and wash the shell unlike quite a few laps neck against evil cervical. However this round the neck is a little short which is not always convenient to maintain it. So at the slightest movement it must replace what has long is not very comfortable especially when the neck are sore ... In short; it is sufficient that the tour was longer for it to be perfect !!! Mr. "manufacturer", think about it !!!!!
