Baseball head protection with temple guard

BCL With Temple Protection

According to the Southern Impact Research Center, the authority on impact protection and testing in the US.
“Almost all ball head impacts in baseball are glancing blows however the temple area is the most vulnerable part of the human body and a direct impact at 30 MPH can kill you.”


Baseball head protection without temple guard

BCL Without Temple Protection

In a sport with so much tradition and strict rules such as baseball we offer the Ball Cap Liner (BCL) that is completely invisible with no temple protection. The BCL has D3O, a ground breaking shock absorbing impact protection material and a very hard metal replacement outer shell.


“I wont let my son go out on the field without a BCL! It’s the best sports protection since the football mouth guard”
