The ZN-918 from the company Zen is a flip-up helmet, widely known as "flip-up" or "openable" as the front part of the helmet can be lifted. Because it is openable, it does not offer the same level of safety as a full-face helmet. It is usually a convenient choice for people who make many short trips with several stops daily. It is made of thermoplastic, a reinforced hard material of high strength. It fastens with a microlock, type buckle which allows you to fasten it easily and quickly. The helmet has the new European type "ECE 22.06" safety specification certification, which ensures that the helmet is tested at 18 impact control points instead of 6 as before. Additionally, it features a sun visor, which is an internal sunshade membrane, like glass, for protection from the sun.
