I bought helmet 5 months ago.
The aerodynamics are not that good. Its too much noisy inside helmet and air also leaks at chin.
Further after 5 months, the chin button for flip up lock got broken.
Despite contacting vector nothing found.
They just dont have a simpme spare part thats easily breakable.
From vectors persoective, i just spent 13000 to use a helemt for 5 months cuz now it cannot be a modular helemt
