Kevin Plank, a former University of Maryland football player, invented Under Armour in 1996 after frustration with cotton T-shirts that absorbed sweat and became heavy during games.
His solution was a moisture-wicking, heat-regulating synthetic fabric that eventually became the foundation of the multi-billion dollar performance apparel brand.

Fabric Innovation Behind Under Armour
Under Armour disrupted the athletic apparel market by focusing on fabric technology rather than traditional sports branding.
Plank studied the properties of synthetic materials used in outdoor gear and experimented with blends that moved sweat away from the skin, resisted odor, and dried quickly.
This focus on performance engineering helped the brand stand out from cotton-based competitors and created a new category of high-performance baselayers.
Early Days and University of Maryland Roots
Plank developed the first prototypes in his grandmother’s basement in Washington, D.C., tailoring garments for local athletes and teammates.
He tested the materials during grueling Maryland football practices, gathering feedback that shaped the fit, durability, and comfort of each design.
These grassroots testing methods provided authentic performance insights that became central to Under Armour’s product development philosophy.
Growth Through Professional Athletes
Strategic partnerships with professional players and coaches in football, basketball, and baseball helped validate Under Armour’s technology.
High-profile endorsements highlighted the functional benefits of moisture-wicking apparel in real game situations, boosting credibility.
This athlete-first approach drove retail adoption and established Under Armour as a serious competitor to established sportswear brands.
Global Brand and Product Expansion
As demand increased, Under Armour expanded its lineup to include outerwear, footwear, and recovery-focused apparel that extended wear beyond training sessions.
Investments in research labs and data-driven design allowed the brand to refine fabric weights, stretch, and breathability for different sports and climates.
Today, the brand serves athletes at all levels, from youth programs to elite professionals, with a product mix that balances performance and everyday style.
