What Features Should Riders Compare Before Buying A China Helmet?

I was recently looking for a helmet for a friend who had started riding his motorcycle more often. He wanted a design that looked simple and felt comfortable, but he also wanted to stay within a reasonable budget. Instead of focusing only on appearance, we compared size, padding, ventilation, visor quality, and overall construction. During the search, we came across the icon china helmet price and wondered how much these features should influence the final buying decision. What do experienced riders usually prioritize?
