 Boys' Sports Trousers & Gym Pants

Beating your goals? It’s about going that little bit harder, that little bit longer, that little bit more sweat. At Under Armour, we built our boys’ sports trousers to give you that little bit extra. We selected performance-grade technologies, advanced materials, and tough designs that actually help you play your sport better. 

Our range of boys’ sports trousers and performance gear includes boys’ joggers, cargo pants, leggings, base layers, golf pants and more. We customised the trousers to the needs of all popular sports - including golf, running, football, and training - but they all share the same Under Armour DNA of innovation, toughness and reliability. 

Under Armour boys’ joggers are ideal for gym sessions, running, track & field, and for wearing between reps. They’re made with soft, cotton-blend fleece, they’re super lightweight, and they wick sweat fast. For sessions in the rain, our boys’ jogging bottoms include water-resistant tech like UA Storm - the fabric repels water, but it’s still super breathable, meaning you stay dry. 

Base layers are essential gear for any training. For winter sessions, our ColdGear® Leggings keep you insulated without adding unnecessary bulk. For warm weather, choose HeatGear® - a super breathable fabric that lets you sweat and keeps you dry. 

Once you’ve selected your boys’ sports trousers, check out our performance shorts or training t-shirts too.
