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.

1. The Real Reasons Under Armour Became Popular

✔ 1) They invented mainstream “compression wear”

UA’s early compression shirts changed the sportswear market.

✔ 2) Moisture-wicking fabrics became their signature

They focus on HeatGear, ColdGear, compression, and training fabrics.

✔ 3) Strong athlete identity

UA is known as a brand for serious training, not fashion.

✔ 4) Affordable compared to Nike

Good performance at a mid-range price.

UA gear is durable, sweat-resistant, and stable for weightlifting.

OEM Insight:
