Giro started in 1985 by creating the first ventilated, lightweight cycling helmet, the Prolight. Today, Giro is a worldwide leader in equipment for cycling, skiing, and snowboarding and the company's goods are worn by millions of riders around the world. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
