Channeling the legendary Giro Nine born over a decade ago, the progressive Nine.10 packs tons of bang for the buck. Style lines borrowed from the Giro Seam combine with our innovative In Form Fit System for the best fit ever made. Plus, we've replaced those pesky, easy-to-lose vent plugs with an ingenious Weather-Strip Vent Shield. 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 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.
