 The "Proudest (and Loudest) Fan" Tee ⚾


Listen, we all know who the real MVP is, and it’s not the kid with the glove—it’s the grandparent in the bleachers with the snacks and the unmatched cheering volume.

Whether he’s hitting a grand slam or just chasing a butterfly in right field, make sure everyone in a three-mile radius knows exactly who you’re rooting for. This shirt is basically a wearable megaphone for your bragging rights.

Why you’ll love it:

  • The "Identify the Talent" Front: Features a bold design that clears up any confusion about which player belongs to you.

  • The "Pro Status" Back: Fully customizable! Add your grandson's Name and Jersey Number to the back so scouts (and other parents) know exactly who the legend-in-the-making is.

  • Soft & Sturdy: Made from 100% Airlume combed and ring-spun cotton. It’s soft enough for a long double-header but tough enough to survive a celebratory post-game hug.

  • Side-Seamed Fit: Looks great whether you’re sitting in a folding chair or jumping up to dispute a questionable call at second base.

Perfect for:

  • Early morning tournaments.

  • Making sure the umpire knows you’re watching.

  • Being the most stylish grandparent on the sideline.

Customization Tip: When ordering, don't forget to fill out the name and number for the back. (Check your spelling—even MVPs have names that are hard to spell!)


Brand Info:

  • Vendor: Merch By Mary Ellen

  • Care: Wash in cold water, tumble dry low, and never iron the design (unless you want your iron to look like a baseball).
