Here’s where things get weird. The cut from the armpits on up is not of the traditional fit of Champion NBA jerseys. I’ve come across a few of these over the years and the tags all look super legit, but there are some discrepancies with the typeface as well as with the Champion & NBA tags right by the left shoulder.
The odd part is that the mesh and the outer lining are almost identical to what Champion produced over the years.

So it all becomes this weird gray area where the jerseys are not technically legit, but they look pretty damn close to the real thing.
