I am shooting in local matches and working my way up to state and regional matches in 2023. I wore a Duluth Trading type poly shirt for competition, but it is starting to wear out. I am not at full on custom jersey level, but I would like something nice and appropriate for competition. Any suggestions? Thanks in advance.

20 bucks.

If you reload you might want to think about joining one of the bullet companies contingency program, spend $50-100 on a jersey, save on bullets and get money for doing well (even in your class).  I paid for my jersey in one match.

I do the Blue Bullets one.

If you go to a USPSA level 2 match or higher they sometimes will have a jersey for that match.  The zero sports custom jerseys have a price for the base that they show at $60.  Not sure how or if any is charged for logos and customization.  Zero sports are also USPSA shooters. Some clubs will have a jersey that you can get through the usual jersey vendors.
