Roc Loc® Sport fit system

One-handed dial with a 7 cm adjustment range and an audible click; Giro says it is ponytail-compatible.

Fuses a tough polycarbonate shell with the impact-absorbing foam liner; Giro says this allows better ventilation and a lighter, cooler helmet.

Deep internal channeling

Channels inside the helmet work with the large vents to force air over the scalp.

How to measure

Wrap a tape measure around your head just above the ears and eyebrows, keeping it level, and read the circumference in centimetres. Where two sizes overlap, head shape decides: try both, or ask us.
