The Velo TT was designed for a single purpose: pure speed against the clock. Developed for time trials and triathlons, this helmet combines cutting-edge aerodynamics, high-quality aesthetics, and in-race comfort in a high-performance package. The removable front vent cover allows you to switch from maximum aerodynamics to increased airflow in seconds, giving you full control over speed and cooling. No compromises. Every element of the Velo TT is crafted with precision. From the revolutionary conical design of the Prizm™ lenses, which expands the field of vision, to the optimized shell shape for minimal aerodynamic drag. Combined with Oakley's advanced TurboDry™ fabric for superior moisture management and a newly conceived 360-Fit system for all-day comfort, the result is a helmet as stylish as it is functional.
