The N129 Triom by Nox is a jet helmet, which, thanks to its open design at the bottom of the face, can be put on and taken off with ease. It is considered one of the lightest types of helmets, however, it leaves a large area of the face uncovered, therefore it is less safe compared to a full-face helmet. It is made of thermoplastic, a reinforced hard material of high strength. The helmet has the new European safety certification "ECE 22.06", 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 film, like glass, for protection from the sun.
