K2DIALED™ FIT SYSTEM:
The K2Dialed™ Fit System creates a custom-fitting helmet no matter what your head shape is.

FULL WRAP LINER:
A comfortable, washable, full-coverage, breathable liner design that wicks away moisture to prevent overheating and seamlessly integrates fit and audio systems.

ACTIVE MATRIX VENTING:
Climate control at the flip of a switch, Active Matrix Venting allows you to regulate the airflow of the helmet vent system with the push of a finger.
