Under Armour is at the forefront of running apparel technology. The new Under Armour Flyweight run tee is made with HeatGear® Flyweight material—lightweight fabric that keeps you cool and dry. The breathable mesh panels create a natural ventilation system while Under Armour's signature Moisture Transport System wicks sweat away from the body.

• Anti-odor technology prevents the growth of odor causing microbes.
• A self-fabric crew neck collar with internal neck tape reduces irritation.
• A mesh panel at each underarm releases excess heat and a large mesh back panel offers enhanced ventilation.
• Design features reflective, heat sealed Under Armour logo at left chest and right hip, and a reflective, heat sealed Under Armour word mark at upper back.
• Flat lock stitching and anti-abrasion labeling prevents chafing and irritation.
