Premium Hybrid Performance Shorts With Built-In Boxer Brief Support

The Diamond MMA Performance Short Brief combines premium athletic performance shorts with a built-in supportive boxer brief liner to deliver unmatched comfort, mobility, and athletic support during training, workouts, and competition.

Designed for athletes who want the support of compression shorts without unnecessary layering or bulk, the Performance Short Brief features a hybrid dual-layer construction with a supportive inner boxer brief and premium outer performance short shell.

Unlike traditional athletic shorts that ride up, bunch, or lack proper support, the Diamond MMA Performance Short Brief is engineered for maximum comfort, flexibility, breathability, and unrestricted movement during high-intensity activity.

Whether you're training in MMA, baseball, hockey, football, lacrosse, CrossFit, strength training, Muay Thai, Jiu Jitsu, running, or tactical fitness, the Diamond MMA Performance Short Brief is built to move with you.
