Questions
I have an XL MX-9 ADV helmet that fits a little too big. I'm wondering if there is a way to get larger pads to tighten the space inside and make it more snug. If so, what liner size and which cheek size would be optimal?
Liners are interchangeable within shell sizes only, which means you already have the thickest liner within your shell size: XS-SM, MD-LG, XL-3XL.
The cheek pads are interchangeable between all helmet sizes; however, you already have the thickest cheek pads in your helmet.

are the M and L liners interchangeable within the same helmet (e.g. if i purchased a medium helmet, can I install a large (L) liner and it will fit properly?
As per the manufacturer, the MX-9 sizes medium and large do share the same shell! The liners are interchangeable. The shell will fit both liners.
