Query: Initial Use

My daughter used it for the first time this weekend in a game. She did do a couple of headers with it on and said that she did notice a difference for the better. It does take some time to get use to and to get it fitted correctly. However, the safety and security that it provides is well worth it. Two team members have had concussions this season. The coach and all the players agreed that they will wear this headgear for the remainder of season and evaluate it's effectiveness at the end.
