The R-Pha 31 by HJC 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 composite fibre, that is, from synthetic fibers that make it flexible and resistant to shock absorption. The built-in wireless Bluetooth connection allows you to connect devices with the same technology, such as a mobile phone. This way, you can answer a call, listen to music, or even get directions from the GPS. If the passenger also has a similar helmet, you can use Bluetooth for intercom, that is, to talk to each other. 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.
