Streamlined design and exceptional venting makes the Giro Sonnet™ helmet a perfect choice for women looking for something fit for long tours or short speedy rides.
- In-Mold™ technology bonds the helmet's tough outer microshell to the impact-absorbent expanded polystyrene liner, creating a light, cool and strong helmet
- Roc-Loc® 5 suspension fits like a dream, holding the helmet in place effortlessly; anchors directly into the liner for great durability
- Wind Tunnel™ vents channel airflow through the Giro Sonnet helmet for maximum cooling in the heat of competition
To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
