Hard-Shell construction sets the standard for what a tough, reliable helmet is meant to be and is characterized by bonding an injection molded ABS shell to a layer of impact absorbing EPS foam. The lightweight EPS forms the inner layer of the “Hard-Shell” and is the primary component that crushes during impact to absorb and dissipate energy. Cradling the EPS is an injection molded ABS “Hard” Shell that protects the EPS from dings and nicks.

K2 Helmets' universal brim designs work in partnership with the helmet-driven topline design and custom engineered strap brackets of our goggle frames, to achieve maximum helmet/goggle fit and compatibility. The combination of Active Matrix™ and Passive Channel™ venting systems on our helmets and carefully distributed lens vents on our goggles, minimize moisture buildup and maximize air circulation, ensuring a clear field of vision and optimized temperature control in various conditions.
