Quick Answer

Under Armour is popular because it introduced performance compression gear, built a strong athlete identity, and focuses heavily on sweat-management fabrics, training apparel, and affordable performance basics.

From my factory experience:
Under Armour uses durable, stable, performance-first knitting that appeals to people who want gear that “feels athletic,” not just stylish.
