Product Description

Introducing the Diamond Tech Vented Tee - Royal Blue. Built for ballplayers who bring the heat on and off the field. Engineered with ultra-breathable, performance fabric, this tee keeps you cool during summer workouts, BP sessions, or while rounding the bases. Strategic ventilation at the back delivers airflow where you need it most to stay locked in and focused. The athletic cut moves with you, giving full range whether you’re making a diving catch or just flexing some drip at the park. Finished with reflective accents and a bold BL101 logo, this tee lets you rep the game with style.

  • Perforations on the back for breathability
  • Seamless hem with vents
  • 100% polyester
