The Zyclo 2 S0 from the company Spyder 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. 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.
