Your best tee, just got better. This is the the original HeatGearŪ Longsleeve, updated with a new ergonomic fit and Anti-Odor HeatGear® fabric. Keeps your arms protected from the turf and keeps you dry, cool, and comfortable until the final seconds tick off the clock. Developed for on-field use and still the most recognizable trademark on gameday. Under Armour's signature compression fit enhances moisture transport and bolsters muscle support.
