The racing shape of the TT COURSE has been studied in a wind tunnel to achieve the best performance without neglecting style and ergonomics. The fine visor mechanism is designed to offer practicality and efficiency. The interiors have been optimized to provide the best performance for comfort and airflow.

Shell

The shell is made in two sizes from advanced thermoplastic ADT, a blend of thermoplastic resins with high impact resistance.

Ventilation

The air ducts allow for air intake, optimal ventilation inside the helmet, and rapid expulsion of hot air. The TT Course has five air intakes at the front and four air ducts under the aerodynamic spoiler.
