The Giro Stylus combines impressive ventilation, a compact shape and amazing fit in a sleek style that's perfect for riders who enjoy great routes as much as a swift pace.
- Acu Dial 2 Fit System - Giro's 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.
- Ventiliation: 26 vents - thrusts cool, fresh air over and around the riders head-while forcing heat and stale air out.
- In-mold construction: EPS liner, polycarbonate shell - fuses the helmet's outer shell with its impact-absorbing EPS liner during the molding process, making the liner literally a part of the helmet. This fusion process reinforces areas around vents and ribs, creating a one-piece 'exoskeleton' that allows the helmet to be lighter, more durable, and better ventilated than traditional designs.
