Diamond K Designs was created by a softball-loving 12-year-old with big dreams and even bigger hustle. What started as a way to raise money for tournaments and lessons has grown into a brand that celebrates the spirit of the game—on and off the field. From dugout laughs to bleacher mom moments, our shirts are designed for the players, parents, and fans who live and breathe softball life.

Every design is inspired by real moments and made with heart. Whether you're dragging the wagon, coaching from the fence, or documenting strike zones (vocally, of course), there's a Diamond K tee for you.

We’re proudly family-run, and every purchase helps fuel a dream, fund the next lesson, and keep the love of the game alive.
