Nope! :-D The size of the helmet actually has more to do with the material used than with a feature. The feature I'm talking about ... well ... focus on the eyes...
It sounds like your implying that there is some sort of lens that covers the opening in the mask. In otherwords, you can make your Batman look like he does in the comics, with white eyes, or as he does in the movies, with his eyes being visible through the cowl.
Regardless of the feature, I'm still not sold on his mask. I'll have to wait until spring to make a final call.
Later.
Maybe there is indeed a lens, but it's an infrared one or something that slides over his eyes?
Afterall, he has that feature in the comics and the animated series?
