At the NFL Annual Meeting, the Competition Committee, Health and Safety Committee and all 32 NFL Owners voted and passed a resolution to mandate that offensive and defensive linemen, tight ends and linebackers wear Guardian Cap for every preseason practice up to the second preseason game. Guardian Cap represents a crucial part of our larger efforts to mitigate head impacts and advance the health and safety for our players.

“Our engineers at the NFL in conjunction with engineers from the players association have tested these in the laboratory and they found that any blow that happens to the helmet with a Guardian Cap over it reduces the force about 10-15% [at NFL speeds]. So if you imagine putting it on both players, an OL and DL for example, you’ve got an additive effect of over a 20% force reduction.”

– Dr. Allen Sills, NFL’s Chief Medical Officer
