Premium Baseball Jersey – Cool Base & Flex Base

Step on the field in style. This MLB-inspired jersey is built from moisture-wicking polyester mesh with reinforced stitching – the same construction players trust, ready to ship today.

📸 Seeing one style? This design is actually available on Men’s Cool Base, Men’s Flex Base, Women’s, and Youth (Boys). Choose at checkout and we’ll craft your jersey to order.

Why This Stands Out

  • 🎨 Pro-Level Finish – Graphics applied with pressure and heat so they become part of the fabric – no cracking, no peeling.
  • 🧵 Flex Base Advantage – Add 12% spandex on Flex Base variants for mobility the replica jerseys can’t match.
  • 👕 Reinforced Seams – Double-stitched shoulders, side vents, and hem. Built to survive slides, catches, and the wash.
  • For Every Fan – Men’s, Women’s, and Youth variants so the whole crew can rep the team.

Jersey Specs

  • Cool Base Men’s: 100% polyester mesh (≈220g). Replica-cut jersey built for comfort and classic ballpark look.
  • Flex Base (Authentic): 88/12 polyester/spandex at ~240g. Athletic stretch fit, moisture-locked performance feel.
  • Women’s: 100% polyester mesh, ~200g, contoured cut, tolerance ±1.2 in. Youth (Boys): 100% polyester mesh, ~180g, kids fit, tolerance ±1.2 in.
  • Jersey fit – all measurements in inches. Between sizes? Size up for the classic loose look.
