Hard Shell – Hard-Shell helmets are built to last and will look good no matter how many trips they make in and out of your gear bag. Hard-Shell helmets protect you from impact thanks to a lightweight EPS foam bonded to an injection-molded and durable ABS shell.

Dual Active Matrix Venting™ – Active Matrix Venting allows you to regulate the airflow of the helmet vent system with the touch of your finger. Controlling large vents with minimal effort results in superior style and function that adjusts on the fly. It's climate control with the flip of a switch.

K2Dialed Fit System™ – An ergonomically inspired three-point adjustable interface maximizes fit and customization. Sizing your helmet with the twist of a dial gives you the ultimate convenience of on-the-fly adjustability.

Baseline Audio System – Pre-installed audio kit with a low-profile speaker that easily connects to your mobile device without hindering the fit or comfort. The on-cord controller is designed for on-the-go usability at your fingertips for talk or tunes.

Full-Wrap Liner – This full-coverage, washable liner snugly cradles your head, creating the unmatched fit of a K2 helmet. The liner features a crown mesh that wicks moisture and breathes to prevent overheating. There are no gaps, which means a better fit and improved comfort.
