The Citystar from the company STR is a jet helmet, which, thanks to its open design at the lower part of the face, can be put on and taken off comfortably. It is considered one of the lightest types of helmets, however, it leaves a large area of the face uncovered and therefore lacks safety compared to a full-face helmet. 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.
