Oakley Velo TT Triathlon Helmet – High-Performance Aero Chrono Helmet

The Oakley Velo TT helmet is designed with a single goal: to go as fast as possible in time trials and triathlons. Developed in a wind tunnel and tested in competition, it combines advanced aerodynamics, perfect vision, and long-distance comfort.

Its streamlined shell minimizes drag, and its wide-field-of-view Prizm™ visor allows you to stay focused on the road even in an aerodynamic position. Thanks to its removable front ventilation cover, you can choose between maximum aerodynamic performance or increased ventilation depending on race conditions.

Ideal for triathletes and time trial specialists looking to gain precious seconds on the bike leg.

Aerodynamics designed for performance

The Velo TT shell is designed to reduce turbulence when the triathlete is in position on the aero bars.

Every detail of the structure has been studied to optimize air penetration and maximize speed for the same developed power.

Oakley Prizm™ visor: perfect vision in aero position

The helmet integrates a conical visor with Prizm™ technology, developed by Oakley to:

• improve contrast on the road

• widen the field of vision

• protect against wind and debris

• improve the overall aerodynamics of the helmet

Comfort and sweat management

The TurboDry™ fabric on the skin-contact areas quickly wicks away moisture to keep the head cool and dry during exertion.

Combined with the 360 Fit System, it ensures stable and comfortable support even during prolonged efforts in time trial position.
