The Nine.9 Junior offers all of the benefits of the adult model, including light weight, great ventilation and a super comfortable fit. But this one belongs to the kids.

Features:

• EPS Liners: Thousands of tests prove that EPS offers the most consistent performance in a wide range of conditions and that gram for gram it absorbs more impact energy than other liner materials. Plus it's incredibly light. No other material brings all of these benefits together.
• In-Mold Construction: In-mold construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner for extra durability without excess weight. The fusion of shell and liner also allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.
• Super Cool: 12 Vents move cool, fresh air through the helmet while radiating 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.
• Sizing: 4 Youth sizes
• Weatherstrip: Weatherstrip vent plugs are simple, lightweight and highly effective for regulating your temperature when you're riding. Just snap a set in to the helmet for a tight seal against the chill, or remove them to let excess heat radiate out.
• Removable Earpads: Removable earpads allow you to adapt your helmet to changes in the weather and riding conditions. They're a snap to install or remove, they lock into the helmet securely and they offer extra warmth whenever you want it - without restricting your hearing.
• Goggle Notch: A channel in Giro helmets that is designed for hassle free positioning of your goggles and a snug, gapless fit with the helmet. It also works in tandem with a security loop at the back of the helmet to keep your goggles with you in the event of a fall.
• Safety Certification: ASTM F2040 Safety certified.
