A couple months ago i installed this Adams football chin strap into my mask. The cup that came with the mask is like a hard styrofoam. I was wanting a tighter fit around the chin, more than what the blue styrofoam cup was giving me.
It felt weird at first... i wasn't sure i wanted to feel like a chipmunk but after a few uses i kind of learned to like it. It does feel a lot more stable now around the chin. Much deeper cup. I don't know maybe it could be my imagination but shots to the mask felt different.. in a good way. Noticed that after the first one.
Had to cut the strap that came with the Adams off to thread the mask strap through it. Nothing that will prevent concussions just something i wanted to try in that area.
