LS2 Advant X Carbon Helmet The lightweight and aerodynamic shell is constructed from 9K Carbon Fiber for lightweight optimal protection. The Advant X Helmet's exclusive modular design features an advanced Fixed Point Pivot mechanism that allows the chin bar to rotate up to 180 degrees with just one hand, providing maximum convenience and accessibility. The Flip-front design allows for quick and easy converting from full-face to open-face mode, without ever having to remove your helmet. Note: Customers have found this helmet to run slightly small and recommend sizing up if you are in between sizes - especially if you measure at the top end of a LG or in between a LG and XL. This helmet is also slightly narrow.
