I bought one for my 10 year old son. He really likes it, and I really like it. Superior protection compared to a foam collar for keeping the head from straining the neck in case of roll over or a hard hit. My son actually had a flip last year. It was all caught on Go pro from a trailing kart, and although his head or neck position was never compromised, The brace kept everything nice and in line. I won’t let him go on the track with out it, period.
