Traditional Mask sold at Dick's Sports--Rawlings PWMX Catcher's Face Mask
The mask that JM showed is considered a "Youth" mask. It is for kids likely of LL and before HS age. It is designed for kids that do not know how to pull off their masks and gives them extra protection.
Rawlings Ai1OS Youth Catcher's Mask / Helmet Combo
The first picture is not outlawed by the rules. The NF Rules only state that the players have to wear a helmet if they are a catcher. The second picture is a combo mask helmet which in no way is required by the rules to be used as stated by UmpireBob.
Is there anything else you are having a hard time figuring out?
Peace
