6. Ruby Motorcycle Helmet Castel ST Roc
Another Ruby Helmet worth mentioning is the Caster ST Roc. It comes with double density inner shell which pushes safety to the next level. Just like the previous one on the list, this helmet features shock absorbency with built-in ventilation ducts, and all fixing elements are made of titanium and aluminum to increase the rigidity as much as possible. In the wall of the helmet, you will find air channels which take out the heated air. It is elegant with the Ruby mark on the top of the helmet, and there are two color choices such as black and silver.
