    Cool under pressure.

    Giro focused on comfort, ventilation, and value when it designed the Sonnet Women’s helmet. The low-profile design keeps the weight down and reduces the spaceman appearance that large, bulky helmets can give you. More importantly, however, Giro built the Sonnet with 25 large vents and its Roc Loc 5 fit system for all-day comfort.

    For the construction of the Sonnet, Giro starts with in-mold technology. This makes it possible to give the Sonnet a low profile with plenty of ventilation. Giro opted for its Roc Loc 5 ratcheting, micro-adjustable retention system. The system allows the wearer to adjust both the helmet’s tightness and vertical position with one hand, so you can fine tune the fit in the saddle.

    • In-mold technology
    • Low-profile design
    • Excellent ventilation
    • Roc Loc 5 system
