How the NBA defines the three categories of jerseys available for retail:
Authentic
The authentic jersey features the same fabrications and embellishments worn by players on-court but offered in regular apparel sizing.
Swingman
The swingman jersey includes nearly all the same visuals as an authentic jersey but integrates a consistent performance mesh fabrication and one layer twill wordmark, name and number applications.
Replica
The replica jersey is a screen-printed derivation of the jersey that highlights basic inserts and design elements.
