Product description
Velo TT, Oakley's fastest TT helmet to date, was precisely engineered to save seconds during intense time trials. It utilizes a Prizm™-enhanced toric shield, a removable vent cover, and the latest aerodynamic shaping to shave seconds when it matters most. It is also equipped with the Oakley TurboDry moisture management system on the lining and straps, and the improved Oakley 360 Fit for comfort during the race.
The Velo TT helmet is equipped with TurboDry fabric on all surfaces that contact the skin, including the straps and inner liner, for enhanced sweat absorption and comfort. The advanced one-way moisture transfer technology of TurboDry ensures skin stays dry, cool, and comfortable, while the straps provide a soft, premium feel against the skin. And best of all, you can remove the liner and wash it normally in a wash bag or hand wash to stay fresh and fast.
The new Oakley 360 Fit system provides a better ride experience and race-day comfort thanks to newly positioned saddle arms and a rubberized dial, while the new cap offers more adaptable sizing and reduces pressure points and hot spots.

More about PRIZM technology
Oakley PRIZM is a technology that revolutionizes the way we perceive the world through sunglasses. This technology allows you to dramatically improve contrast, sharpness and colour resolution, meaning you can see things that would otherwise remain hidden. The principle of operation of Oakley PRIZM is that it filters certain wavelengths of light to improve your visual experience. Each lens is designed to filter out specific colours, increasing contrast and helping to reveal even the smallest details.
Main benefits
- fine-tunes visual acuity so you can see better and clearer and react sooner
- improves colour recognition and allows you to focus on what you need to see
- optimizes the ability to see and track moving objects in your field of view
How PRIZM technology works
Thanks to specially formulated additives added to the lenses during manufacturing, Prizm filters out optical "noise" from light that interferes with colour discrimination. You can think of this technology as ultra-precise color tuning that is designed specifically for your sport or activity environment.
