Engineered for performance, designed for confidence. The C-IN2 Pro Boxer Brief features a 5-inch inseam for the perfect balance of coverage and mobility. Made with high-performance fabric that wicks away sweat and dries fast, this boxer brief keeps you cool and comfortable through workouts and everyday wear. Cooling mesh zones add breathability where you need it most, while the sculpted fit stays put no matter how you move.
