Baseball Jersey – Moisture-Wicking Performance Fabric

Ball players know: the jersey matters. Ours is cut from breathable polyester mesh, reinforced at every seam, and printed so the colors pop under stadium lights.

📸 Don’t let the mockup fool you – this design prints on all 4 jersey styles: Men’s Cool Base, Men’s Flex Base, Women’s, and Youth. Your pick, your fit, ready to ship today.

What Makes It Hit Different

  • 🎨 Built to Last – Fade-resistant graphics that stay vibrant from opening day to the playoffs.
  • 🧵 Flex Base Advantage – Add 12% spandex on Flex Base variants for mobility the replica jerseys can’t match.
  • 👕 True-to-Sport Sizing – Jerseys are built loose for layering. Between sizes? Size up for that classic ballpark fit.
  • ⚾ In Stock – Each jersey is stocked ready to ship. No bulk warehouse stock – yours is made just for you.

Technical Details

  • Cool Base (Replica): 100% polyester mesh at ~220g. Traditional loose fit for that stadium-style drape.
  • Men’s Flex Base (Authentic): 88% polyester / 12% spandex, ~240g – performance fit with stretch, tolerance ±1.5 in.
  • Women’s: 100% polyester mesh, ~200g, contoured cut, tolerance ±1.2 in. Youth (Boys): 100% polyester mesh, ~180g, kids fit, tolerance ±1.2 in.
  • Note: Flex Base runs more athletic than Cool Base. If you prefer a looser fit, stick with Cool Base or size up on Flex Base.
