Hey parents, this Sport-Tek sleeveless tee is perfect for active boys! The PosiCharge mesh material is seriously breathable - keeps them cool even during intense games or practices. The reversible design is genius - it's like getting two shirts in one! One side has colored piping on the shoulders and sides for that athletic look, while the reverse is white mesh. The rib knit collar is comfortable and doesn't rub or chafe. Double-layer construction means it's durable enough to handle rough play and multiple washes. The tag is conveniently placed at the hem so it doesn't irritate the neck. Sizes range from XS (4) up to XL (18-20), so you can find the perfect fit as they grow. The material wicks moisture away from the skin, so no more soaked shirts after practice. It's lightweight at 3.2 ounces - barely feels like they're wearing anything. Great for basketball, soccer, running, or just playing outside. The open layers make it easy to add team numbers or logos if needed. Seriously, this might become their favorite practice shirt - it's that comfortable and functional.
