Words from Tournament Directors & Players

Our gear from Diameter Apparel was both beautiful and practical. I've seen many of the players from the tournament regularly wearing their apparel and loving it. As a matter of fact, I'm wearing my shirt as I type this! The quality of their product is what stands out. The apparel is beautiful, functional, and really feels like it serves the modern disc golfer. — Ben Smith | TD

I wear Diameter Apparel gear because it's comfortable and stylish, and makes me feel great. This makes me play with more confidence, which is great for my game! — Kat Johnson | FPO Player

Sustainable Materials and Stunning Designs

All our polos and jerseys are made with materials made from recycled water bottles! It does cost us a bit more, but it's worth being part of the solution. By ordering from Diameter Apparel, you become part of the solution too.
