Spin in the perfect fit with the Phase helmet, now available with an optional MIPS liner for increased protection. Subtle contouring and perfectly placed Active Matrix ventilation combine for under-the-radar styling, functional fit, and supreme comfort.

- HARD SHELL CONSTRUCTION: Hard-shell helmets are built to last and will look great no matter how many trips they make in and out of your gear bag. Hard-shell helmets protect users from impact thanks to lightweight EPS foam bonded to a durable, injection-molded ABS shell.
- ACTIVE MATRIX VENTING: Climate control at the flip of a switch. Active Matrix venting allows the user to easily regulate the airflow of the helmet's venting system.
- FULL WRAP LINER: A comfortable, washable, full-coverage, and breathable liner design wicks moisture to prevent overheating and seamlessly integrates K2's fit and audio systems.
- K2DIALED™ FIT SYSTEM: The K2Dialed™ Fit System creates a custom-fitting helmet no matter what your head shape is. An ergonomically inspired three-point adjustable interface maximizes fit and customization with the twist of a dial. This allows for the ultimate convenience of being able to make fit adjustments on the fly.
- BASELINE AUDIO SYSTEMS: Pre-installed audio kit with a low-profile speaker that easily connects to your mobile device. The on-cord remote control your talk and tunes right at your fingertips.
