Official-Style MLB Jersey — In Stock

This isn’t a generic tee with a number slapped on. It’s a real-deal baseball jersey: moisture-wicking mesh, double-needle stitching, and athletic tailoring that moves with you.

📸 The mockup shows one style – but this design ships on Men’s Cool Base, Men’s Flex Base, Women’s, and Youth (Boys). Pick your variant, size, and we’ll make it just for you.

Jersey Features

  • 🎨 Stadium-Grade Print – Bold, vibrant graphics that hold up to full seasons of wear, washes, and cheers.
  • 🧵 Lightweight Polyester – Athletic mesh fabric that breathes, dries fast, and feels great in the summer heat.
  • 👕 Cool Base vs Flex Base – Cool Base for that traditional replica look; Flex Base for the authentic, moisture-locked athletic fit.
  • ⚾ Cheer or Play – Worn on the field or in the stands, this jersey delivers the same premium feel.

Material & Construction

  • 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.
