From batting practice to season opener, this jersey delivers. Lightweight polyester mesh keeps you cool, athletic fit keeps you sharp, reinforced construction keeps it game-ready.

Why You’ll Love This Jersey

  • 🎨 Pro-Level Finish – Graphics applied with pressure and heat so they become part of the fabric – no cracking, no peeling.

  • 👕 V-Neck Construction – Classic baseball V-neck with reinforced stitching. Looks sharp, holds up over seasons.
  • Season After Season – Built to hold up to game days, laundry cycles, and years of wear.

Build Specs

  • Cool Base (Replica): 100% polyester mesh at ~220g. Traditional loose fit for that stadium-style drape.
  • 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.
