Under Armour Gameday Armour Extended Slider - Men's Under Armour won't let you hit the dirt without being completely covered. That's why they made the Gameday Armour Extended Slider, with a 17" over-the-knee length. Durable, stretch-woven fabrics remain lightweight while holding superior HeatGearŪ technology. Slide zones are protected with knee padding and reinforced side panels. That means no bulk, no loss of feel, and no tearing mid-season. Includes a ventilated mesh cup pocket. 84% polyester/16% spandex. Imported.
