Premium MLB-Style Jersey — Player-Grade Construction

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.

What Makes It Hit Different

  • 🎨 Pro-Level Finish – Graphics applied with pressure and heat so they become part of the fabric – no cracking, no peeling.
  • 🧵 Moisture-Wicking Mesh – Breathable polyester mesh pulls sweat away fast. Stay cool from first pitch to final out.
  • 👕 Four Fits, One Design – Men’s Cool Base & Flex Base, Women’s contoured cut, and Youth sizing. Every fan gets their fit.
  • ⚾ Season After Season – Built to hold up to game days, laundry cycles, and years of wear.

Build Specs

  • Cool Base Men’s: 100% polyester mesh (≈220g). Replica-cut jersey built for comfort and classic ballpark look.
  • Men’s Flex Base (Authentic): 88% polyester / 12% spandex, ~240g – performance fit with stretch, tolerance ±1.5 in.
  • Women’s: 100% polyester mesh at ≈200g with a contoured silhouette. Youth (Boys): 100% polyester mesh at ≈180g, sized for ages 6–20.
  • 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.
