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.

• CONICAL LENS WITH PRIZM TECHNOLOGY: A first of its kind, Velo TT features a revolutionary conical lens that increases FOV and supports the overall shell shape and design.
• ACCESSORY LENSES: Accessory lenses are available in Prizm Road and Prizm Low Light.
• TT SHELL SHAPE: Aero-inspired design offers low drag performance that outpaces most competitor aero helmets—even with vents. *At certain speeds and in certain positions
• REMOVABLE VENT COVER: When you need more ventilation to stay cool, Velo TT comes with a removable vent cover in the front of the helmet that easily disconnects and snaps back in place.
• LINING: Velo TT features TurboDry fabric on all next-to-skin surfaces, including straps and the interior liner, to enhance sweat absorption and comfort. TurboDry’sadvanced one-way moisture transfer technology ensures the skin stays dry, cool, and comfortable, while the straps provide a soft, premium feel against the skin. Best of all, you can remove the liner and wash normally in a laundry bag or hand wash to keep you fresh and fast.
