Featuring our proprietary KILOMAX weight system, these shorts allow you to strategically add resistance directly to the quads, the primary drivers of sprinting and acceleration. With four precision weight pockets, two on the side quad and two on the front quad, APEX gives you complete flexibility in load distribution. Emphasize acceleration on drive days.
