Grinding out your training in hot, humid conditions? UA HeatGear® is engineered to keep you dry, cool and comfortable - so you can focus on your workout, without distractions. To help with temperature control, we laser cut panels and meshes into our men’s short sleeve shirts and tops, placing them where you need them to encourage ventilation and avoid overheating. And we used anti-odour treatments which help prevent the build up of odour-causing microbes, meaning our sports t-shirts for men last longer. Under Armour men’s short sleeves shirts are specifically designed to facilitate the dynamic movements you do in your sport - whether it’s shooting hoops, smashing the battle ropes or sprinting along trails. You’ll find things like 4-way stretch, a design which means your top moves with your body, but doesn’t pull out of place and ride up. Many of our short sleeve men’s shirts use UA SmartForm, a technology that makes the t-shirt mould to your body shape for a custom feel. You’ll be wearing this gear in practically every training session you do. That’s why we built our men’s short sleeve shirts and tops to give you tough, reliable and innovative designs that actually make you perform better. Because when you’re working to smash your goals, you need equipment that works as hard as you. We use this ingenious fabric in a wide range of our gear for different sports - from running to golf, football to gym training, basketball and more.
