Men's Ninja Suit™ 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.

Constructed with our NinjaTech Air™ shell and built-in NinjaTech™ compression liner, this system delivers lightweight mobility on the outside with second-skin performance underneath—designed to move as one through every phase of training.

Description

Built on the foundation of our original Signature Ninja Suit™ men's no-gi 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 built-in NinjaTech™ compression liner, delivering a secure, second-skin fit with breathable, sweat-wicking performance. Skip the extra layers and experience locked-in support, reduced friction, and distraction-free training.

The FlowFit™ waistband—featuring dual elastic banding and a hidden internal drawstring—ensures a secure, low-profile fit without irritation or bulk, so you stay focused on performance, not adjustments.

Doubly reinforced flatlock stitching throughout enhances durability and flexibility, built to withstand the demands of high-intensity grappling.

As part of the Signature Ninja Suit™ system—powered by NinjaTech™ performance fabrics, these shorts are designed to pair seamlessly with our men's performance rashguards 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.

Sharper. Lighter. Stronger.

Built for athletes who want less bulk, more precision, and gear that keeps up with their pace.

Designed for athletes. Built for how you move.
