15 Super Cool Vents: Super Cool™ vents pull cool, fresh air into the helmet while pushing heat and stale air out. By maximizing efficiency and optimizing vent shapes, the collective cooling power of Super Cool vents helps to regulate your core temperature and keep you feeling fresh all day

You can easily fit a pair of goggles over or under the Giro G9 Jr Helmet.

The In Form™ fit system makes it easy to dial in a custom fit in seconds – even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability while the vertical tuning feature accommodates different goggles and head shapes for a custom fit, free of gaper gap.

In-mold construction: fuses a tough polycarbonate outer shell with the helmet’s impact absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets

Super Fit™ Engineering is the foundation of Giro’s product design process. Every new Giro product is designed with reference to their database of anatomic measurements and rider input. They then test the design repeatedly in the lab and in the hands of riders so they can gather feedback and make refinements to create a final product that fits and performs at the highest level
