Greymule, the Kevlar one is heavier than the less costly ABS plastic model, also by All Star. Other than one is bullet-proof and paintable - and heavier - no difference. EXACTLY the same shape, so the vision is the same. The costlier ones have a cage made of titanium... All Star calls it "pro-tanium". I am going into my fifth season with an All-Star mask, and it seldom comes off. Between innings of course, but I am not prone to taking it off during play. There are times that I have - notably on a rundown where I may take the third base call... other than that... not much in all the years. They are the best and I have yet to find someone say that they did not love it once they tried it.
Best of luck with yours, should you get one.
