Go to
http://www.uniforms4sports.com. Click on the licensed USSSA apparel logo. You want to order the red mesh shirt, the black shorts (if you want to wear shorts) or the grey slacks. The red mesh is for USSSA softball, the navy is for USSSA baseball. You will also want to order the red and black cap, and possibly a red jacket for those cool spring nights that you will be umpiring on.
