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.

📸 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.

Jersey Features

  • 🎨 Pro-Level Finish – Graphics applied with pressure and heat so they become part of the fabric – no cracking, no peeling.
  • 🧵 Breathable & Cool – Engineered mesh fabric with built-in airflow. Designed for real game-day conditions.
  • 👕 Cool Base vs Flex Base – Cool Base for that traditional replica look; Flex Base for the authentic, moisture-locked athletic fit.
  • Season After Season – Built to hold up to game days, laundry cycles, and years of wear.

What It’s Made Of

  • Cool Base Men’s: 100% polyester mesh (≈220g). Replica-cut jersey built for comfort and classic ballpark look.
  • Flex Base Men’s: 88% polyester, 12% spandex (≈240g). Pro-level stretch for a tailored, performance fit.
  • Women’s: 100% polyester mesh, ~200g, contoured cut, tolerance ±1.2 in. Youth (Boys): 100% polyester mesh, ~180g, kids fit, tolerance ±1.2 in.
  • Fabric note – mesh is soft against the skin but built for performance: quick-dry, moisture-wicking, breathable.
