ACU DIAL ™ 2
Our Acu Dial 2 fit system offers the convenience of single-handed adjustment, plus variable-fit belt anchor points providing a brilliant fit and feel. Acu Dial 2 is slim, durable, and even ponytail-compatible.
In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
WIND TUNNEL™ VENTILATION
Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents
in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing
heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride.
