Great piece of equipment
My son plays competitive lacrosse and football. We had seen the collar on another teammate and inquired about it. After researching it we purchased immediately. I'm a physician and understand that while this piece of equipment cannot prevent concussions 100% it does help reduce them and the severity of its impacts. Having FDA approval and a high rate of protection really is impressive. Anything we can do to protect our athletes only benefits them even more and any extra protection is 100% better than nothing.
