Short Sleeve T-Shirts

When you’re giving it your all, be confident that our short sleeve shirts are giving it right back. Short sleeves are a staple of any athlete’s wardrobe, and that’s why we’ve invested so much in making our short sleeve tops the best they can be. You’ll be wearing this gear session after session – so it needs to count.

Under Armour short sleeve shirts are packed with unique features which you’ll notice when grinding it out at the gym, at training, at events. Built on years of R&D, we packed them with technologies that actually help you perform better.

Take UA RUSH™, an infrared technology that reflects your body’s energy back to you when you’re training. We mixed minerals into our fabrics that respond to your body temperature, working a bit like a sauna. This boosts circulation - helping you work out harder while also improving your recovery rate too.

Many of our short sleeves come with Iso-Chill, a fabric blend that keeps you cool - and actually feels cool to the touch. That can be especially valuable in a short sleeve running top when you’re training in the heat. UA SmartForm, meanwhile, means your short sleeve top moulds to the shape of your body, eliminating chafing. And our short golf sleeves deliver UPF 50+ coverage, offering UV ray protection on the brightest days.

Our short sleeve shirts also give you smart design features that eliminate distractions and help you focus. We placed smart vent panels on the backs and underarms to boost airflow. They come with anti-odour technology which keeps ‘em fresh for longer. And of course, our short sleeve shirts are stretchy, feel soft, and wick away moisture fast.
