This helmet conforms to, or exceeds EU Standards only.

Acu Dial™:

The Acu Dial system combines single-handed adjustment with a full fit band that brings a quick, sure ponytail-compatible fit in our line of Universal Fit helmets.

In-mold Construction:

In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows us to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.
