Catcher's Gear Questions

[baseballpadre]

Hi, quick question about the rules regarding my son’s catcher's equipment. I was wondering about the difference between the full, hockey-style mask and the old-school style that goes over the skull cap. I recently purchased the facemask style that goes over the skull cap for my son who has recently picked up catching a big way. I got him this mask but a few of the parents at our workouts have made comments about some regulations or rules I was unaware of. In my nervousness, I just ordered this mask as well that looks a lot safer but I know it doesn't have that cool pro look my son wants. Should I bring both with me just in case? Or does anyone know how this aspect of the game is governed? Anything helps!
