## Summary

Boys' long sleeve HeatGear baselayer training top in black with a white logo, designed for moisture-wicking and heat management during athletic activities.

## Description

Our HeatGear® long sleeve baselayer is built for boys training and competing in the heat. Engineered with ultra-light HeatGear® fabric, it delivers full-arm coverage that wicks sweat and stays cooler in hot conditions. Made for layering under pads/jersey or wearing as a solo training top. This shirt is designed for arm coverage in hot weather, not for cold-weather layering.
