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 lightweight EPS foam bonded to an injection molded and durable ABS shell.

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

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.

Channels on the inside surface of the EPS direct air-flow between your head and the helmet, removing moisture and excess heat for all day comfort.

Certified by North American bicycle helmet safety standard and European bicycle and skateboard helmet safety standard.
