Men's Workout Shirts & Tops - Outdoor

Whether it’s going for a hike in the blazing heat, running a 5K in the freezing cold, or something else that’ll have you test yourself outdoors, comfort means everything. Find the right fit and the right gear you need to perform at the highest level with Under Armour men’s outdoor shirts and baselayer shirts, built to make you better.

Stay locked in with men’s outdoor shirts made with materials that keep you warm and comfortable when the weather takes a turn, keep you cool when the sun starts to beat down, and help keep you dry when you test the waters.

Find outdoor T-shirts, long sleeve outdoor shirts, and crewnecks that are built for performance. Our crewnecks keep sweat out, help your body breathe, and are light (yet heavy enough) to keep you warm. Get the same with our quick-drying T’s designed with graphics to let the world know you take your adventures seriously.

Working out in the bitter cold is challenging enough. Men’s outdoor hoodies built with ColdGear® absorb your body heat with their interior print, keeping the warmth in and the cold air out so you can focus on the work ahead. Fleece men’s outdoor hoodies keep you just as warm and are super soft on the inside, so you’re comfortable when the weather dares you not to be.
