not sure, Mario did not wear such an item.
with the set up needed for the embroidery it stands to reason there was a run of these.
how many? No idea.
Jim Cunningham when he sold his Confente Pista had what was purported to be a Confente jersey, it did use the same basic colors of Mario’s USA transfer set, was curious as it did not have a zipper, appeared as more of a T-Shirt with a embroidered herald patch.
i did not see those back in the day either.
caps? Yes. Water bottles? Two versions.

This jersey I will go as far to say was not professionally designed.
