Game-Day Ready – Premium MLB-Inspired Jersey

The look of the majors, made for you. This MLB-style jersey features performance mesh fabric, athletic cut, and crisp, durable graphics on every variant.

📸 Image is a preview – this jersey is available in 4 variants: Men’s Cool Base (Replica), Men’s Flex Base (Authentic), Women’s, and Youth (Boys). Select your style and size at checkout.

Why This Stands Out

  • 🎨 Sharp, Crisp Design – Every logo, number, and letter is printed with precision for a jersey that looks game-ready out of the box.
  • 🧵 Flex Base Advantage – Add 12% spandex on Flex Base variants for mobility the replica jerseys can’t match.
  • 👕 Cool Base vs Flex Base – Cool Base for that traditional replica look; Flex Base for the authentic, moisture-locked athletic fit.
  • ⚾ For Every Fan – Men’s, Women’s, and Youth variants so the whole crew can rep the team.

Build Specs

  • Men’s Cool Base (Replica): 100% polyester mesh, ~220g – classic loose replica fit, tolerance ±1.5 in.
  • 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.
  • 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.
