The Giro Nine.10 Junior Helmet represents form complimenting function that can be applied to any terrain or riding style. Incredible comfort via our In Form fit system & a great price make this a perfect all around helmet. The In Form™ 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 6 cm of adjustment & enhanced stability while the vertical tuning feature accommodates different goggles & head shapes for a custom fit, free of goggle gap. Super Cool™ vents pull cool, fresh air into the helmet while pushing heat & stale air out. By maximizing efficiency & optimising vent shapes, the collective cooling power of Super Cool vents helps to regulate your core temperature & keep you feeling fresh all day. In-mould construction fuses the helmet’s outer shell with the impact-absorbing EPS liner. The two materials are fused together, & one is reinforced by the other. This ‘exoskeleton’ allows us to engineer helmets that are lighter, more durable & better ventilated. Small: 52cm
