My son also has this helmet and got a concussion. However, in his case no helmet would have stopped it. He was hit in the head by a cheap shot unavoidable cross check. His teammate also was hit by a goalie charging out of the cage with his head down like a raging bull. I think coaches should teach the game of lacrosse and not football. I also think refs should take a serious look at these hits and determine a punishment greater than a 2 minute unreleasable penalty. I would hope cascade and warrior didn't fudge their data and if stx is doing this for marketing, then shame on them.
