For the athlete who builds their own race day system, the Performance Tri Short is the ultimate engine room. We engineered this short to be a concentrated hub of power and flexibility, allowing you to pair it with your preferred Tri Top for a truly personalized setup.

The Foundation of Power: The entire short is crafted from a single, high-performance material: Kailua fabric. With its exceptional 35% Elastane content, Kailua provides powerful, uniform compression across your quads, hamstrings, and glutes. This active support system reduces muscle oscillation, delaying fatigue and allowing you to sustain a higher power output for longer.

Despite its compressive nature, Kailua's four-way stretch moves with your body, offering an unrestrictive feel through every pedal stroke and running stride. Inside, our proven REGNA 4D chamois delivers critical protection and comfort for hours in the saddle, yet its minimalist design remains virtually imperceptible on the run.

This is more than a short; it's a commitment to performance, built to withstand the rigors of triathlon. When calibrated to your exact dimensions with our PHOTOtoFIT™ AI technology, it becomes the most powerful and comfortable short you will ever own.
