The velo tt is built for one purpose: pure speed against the clock. Designed for time trials and triathlons, this helmet blends cutting-edge aerodynamics, premium optics, and race-day comfort into one elite performance package. Its removable front vent cover lets you switch from maximum aero efficiency to increased airflow in seconds, giving you complete control over speed and cooling. No compromises. Every element of velo tt is precision-engineered. From its revolutionary conical prizm™ lens design that expands your field of view to its optimized shell shape for minimal drag. Pair that with oakley’s advanced turbodry™ fabric for superior moisture management and a redesigned 360 fit system for all-day comfort, and you’ve got a helmet that’s as fast as it is functional.
