Lightweight and durable these K2 Crossfire helmets feature adjustable venting and sizing. This helmet is equipped with a polycarbonate shell over lightweight EPS foam, so it's rugged but remains lighter than a typical hard shell. Active Matrix ventilation has sliders to increase air flow on hotter days and the new K2 Dialed fit system allows one-handed, glove-friendly adjustments. These helmets are brand new from K2. - Polycarbonate Shell - EPS Foam - Active Matrix Ventilation - K2 Dialed Fit Sizing
