The Under Armour Boys' Locker T-Shirt (Model 1305845) is a compression-fit base layer engineered for young athletes who need muscle support and moisture management during training, sports practice, or active play. Constructed from Under Armour's signature HeatGear fabric, this shirt delivers a tight, second-skin fit that enhances circulation and reduces muscle fatigue without restricting movement. The Black colorway offers a versatile, team-friendly appearance that coordinates with any uniform or athletic shorts. The lightweight, four-way stretch material wicks sweat away from the body and dries quickly, keeping boys cool and comfortable during intense physical activity. Anti-odor technology prevents the growth of odor-causing microbes, allowing extended wear between washes. Flatlock seam construction eliminates chafing against the skin, while the crew neck and short sleeves provide coverage without overheating. Ideal for football, basketball, soccer, gym class, or outdoor training, this compression shirt serves as a foundational piece for layered athletic wear or stands alone as a performance top.

Common Q&A's:
-
What is the difference between HeatGear and ColdGear compression?
HeatGear is designed for warm conditions, wicking sweat and promoting cooling airflow during hot weather or intense indoor activity. ColdGear provides thermal insulation for cold weather performance. This Locker T-Shirt utilizes HeatGear for optimal comfort in temperatures above 55 degrees Fahrenheit. -
Should I order my son's regular shirt size or size up for compression fit?
Order the standard shirt size for intended compression performance. The garment is engineered to fit tight against the body; sizing up will result in a looser fit that compromises muscle support and moisture management benefits. If between sizes, consider the larger size for growing youth. -
Can this shirt be worn as an outer layer or only as a base layer?
While designed as a compression base layer, the sleek Black appearance and crew neck styling allow it to be worn as a standalone athletic shirt for training or gym class. The tight fit will be visible, which is standard for athletic compression wear.
