Boys' Long Sleeve Tops & Shirts

A couple of boys' long sleeve tops are pretty much essential for your sport. They’ll keep you warm when training in cold, windy or wet weather, and they also let you layer up to find the ideal temperature. Under Armour boys’ long sleeve shirts do all the basics, but they also include advanced designs, materials and technologies that help you work out better. 

Our boys long sleeve t-shirts are engineered using some of our most advanced technologies, so you can find the right top for your type of training and whatever the weather is doing. For winter workouts, ColdGear® technology gives you a dual-layer fabric that keeps you warm, but remains breathable and sweat-wicking.
