Under Armour’s Performance Tech boxer briefs sit in the brand’s training-first underwear range, competing with moisture-wicking staples from Nike and adidas. The focus here is on comfort under movement: lightweight fabric that feels smooth against the skin, with breathability aimed at reducing sweat build-up during gym sessions, runs, or long days on your feet. Coming as a 3-pack in black, it’s a simple restock if you prefer consistent fit and feel across the week.

Who are these best for?

If you find cotton boxers get clammy or ride up, this style makes sense. The Performance Tech material is geared towards staying drier and feeling less bulky under shorts or slim trousers. A supportive, close fit tends to work well for training and commuting; if you prefer a looser cut, you may want to size with that in mind.

  • 3-pack: useful if you want matching pairs for rotation and wash days
  • Sizes S–XXL: broad sizing range for most builds
