Introducing the Diamond Tech Vented Youth Tee - BL 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

Love love love
I am so glad I was able to snatch this shirt for my son during their second drop. He has worn it non stop and loves it. I ordered him a large so he can wear it a bit longer.
