Premium Baseball Jersey – Cool Base & Flex Base

Whether you’re a weekend league hitter or a lifelong fan, this jersey delivers. Athletic fit, moisture-wicking mesh, and crisp graphics that don’t peel after the first wash.

📸 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.

The Good Stuff

  • 🎨 Pro-Level Finish – Graphics applied with pressure and heat so they become part of the fabric – no cracking, no peeling.
  • 🧵 Performance Ready – Quick-dry polyester mesh built for movement. Stays comfortable whether you’re playing or cheering.
  • 👕 V-Neck Construction – Classic baseball V-neck with reinforced stitching. Looks sharp, holds up over seasons.
  • Premium Construction – Industry-standard jersey-grade polyester with pro-level finishing details.

Fabric Breakdown

  • Cool Base (Replica): 100% polyester mesh at ~220g. Traditional loose fit for that stadium-style drape.
  • Flex Base (Authentic): 88/12 polyester/spandex at ~240g. Athletic stretch fit, moisture-locked performance feel.
  • Women’s: 100% polyester mesh at ≈200g with a contoured silhouette. Youth (Boys): 100% polyester mesh at ≈180g, sized for ages 6–20.
  • Fabric note – mesh is soft against the skin but built for performance: quick-dry, moisture-wicking, breathable.
