What to know about Under Armour
Under Armour is a publicly traded American sportswear company (NYSE: UAA/UA) founded by Kevin Plank in 1996 and headquartered in Baltimore. It built its business on HeatGear and ColdGear compression base layers and now spans training, running, basketball, team sports and golf, with the Curry Brand signature line as its main footwear franchise. Founder Plank returned as CEO in April 2024 and is running a multi-year reset that cuts product volumes, reduces promotions and trims wholesale distribution. It also owns sustainability label Unless Collective, acquired in 2024.
How Under Armour fits
Overall fit
slightly small
Under Armour uses its own Compression / Fitted / Loose labelling, and shoppers commonly report the athletic cut runs snugger than mainstream US sportswear, so a size up is a frequent recommendation for anyone who isn't slim-built.
Tip: Most people are safest taking their usual size in 'Loose' fit and going up one size in anything labelled 'Fitted' or 'Compression'.

By category
| Category | Runs | Shape | Size advice |
|---|---|---|---|
| Hoodies & sweatshirts | slightly small | trim athletic fit through chest and sleeves, not boxy | Take your normal size for a close fit, or size up if you want to layer over a base layer or prefer a relaxed drape. |
| Jackets | slightly small | athletic, close through the chest and sleeves with limited room for bulky layers | Consider sizing up if you plan to wear a hoodie or thick midlayer underneath. |
| Shirts & overshirts | true to size | golf and woven performance shirts run in a straight athletic cut rather than a dress-shirt cut | Order your usual size; go up if you carry width in the chest or shoulders, as the armholes can feel tight. |
| T-shirts & graphic tees | runs small | Fitted and Compression styles cling to the torso; Loose styles are closer to a regular athletic cut | Size up one in Fitted/HeatGear compression tees; stay true to size in the Loose/Tech line if you want a normal T-shirt feel. |
| Trousers & pants | true to size | tapered joggers and slim-straight training/golf pants | Stick with your normal waist size but check inseam options, since the legs are frequently reported as long. |
