Boys’ Long Sleeve Shirts for All Seasons

The work you put in doesn’t stop once the weather gets chilly. If anything, it might just really start kicking into gear depending on the sport you play. But even if it’s your offseason, there’s training to do. With our boys’ long sleeve shirts, we pack them with game-changing technology and fabrics that work to help push you through tough weather and tougher workouts. Perfect for cold days in school, at the park, and at the field, these long sleeve shirts for boys are built to make you better.

Long sleeve compression shirts give you that next-to-skin feel that players love underneath a jersey. They help you feel yourself in space, and with the help of 4-way stretch fabric, you move more comfortably in every direction no matter which way your body twists and turns.

Our classic baselayer Under Armour boys’ shirts with ColdGear® and HeatGear® fabrics keep you ready to go any day of the week. ColdGear® keeps you warm and dry in the cold. And, with HeatGear®, you can stay cool. That means you’re not weighed down by hard workouts and hard work.

Find plenty of styles of boys’ long sleeve shirts, too. Quarter-zip, ½ zip, full zip. Some with soft, light, and warm Armour Fleece®. Those with loose fits, those with fitted ones, and others with compression. We use flat seams to prevent irritation and add mesh panels to some of our long sleeve boys’ shirts to dump excess heat. Check out more baselayers that help make you better all season long.
