SB13 introduced by the Traderhouse company that operates SIMPSON in Japan.
The design features side and front vents that allow efficient airflow to be captured through the rear vents and allow internal heat and moisture to be discharged through the rear vents.
Since it is a carbon edition, it is very light compared to the Simpson helmet that is the same type of Simpson helmet with a large shell.
Recommended for long touring and for those who value style.
