The ZN-737 by Zen 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, which makes it less safe compared to a full-face helmet. It is made of thermoplastic, a hard material, heavier compared to other materials. It secures with a microlock type buckle, allowing you to fasten it easily and quickly. The helmet has European safety standard certification "ECE 22.05", which ensures that the helmet has been tested for drop, impact, and object penetration. Additionally, it features a sun visor, an internal sunshade, like a glass, for protection from the sun.
