Men's Signature Jiu Jitsu Board Shorts - Pro Fit

Meet the next evolution of performance. Our Signature Ninja Suit™ board shorts—now in Pro Fit, engineered with a more streamlined silhouette, reduced bulk, and upgraded durability for high-level training and competition. Description Built on the foundation of our original Signature Ninja Suit™ shorts, the Pro Fit version refines every detail for a faster, more technical feel on the mat. A slightly shorter inseam and streamlined cut reduce excess fabric and eliminate drag, giving you unrestricted mobility through every scramble, shot, and transition. The result is a cleaner, more athletic silhouette designed to move with you—not against you. These premium men’s board shorts feature our signature built-in compression liner, delivering a secure, second-skin fit with breathable, sweat-wicking performance. Skip the extra layers and enjoy locked-in support, reduced friction, and distraction-free training. The no-velcro waistband with internal drawstring ensures a secure, low-profile fit without irritation or bulk, while doubly reinforced stitching throughout adds the durability needed to handle the demands of high-intensity grappling. As part of the Signature Ninja Suit™ system, these shorts are designed to pair seamlessly with our performance tops for a complete, competition-ready no-gi kit. For competition use, our black Pro Fit Signature shorts are designed to meet International Brazilian Jiu-Jitsu Federation uniform requirements—delivering a modern, streamlined fit without compromising compliance.
