So Engineered for the elite. The Muscle-Fit "Brothers" Shorts are designed for the athlete who leaves it all on the gym floor. Combining the natural breathability of high-grade cotton with the technical support of a high-performance inner liner, these shorts are built to handle heavy squats, explosive box jumps, and high-intensity sprints without the distraction of chafing.
