Airoh TRR Trials Helmet Liner (2018 to 2024)

Spare liner to fit the Airoh TRR trials helmets from 2018 to 2024

The helmets come with 2 different shell sizes, the smaller one does the XS, S & M sizes, the larger shell does the L, XL, & XXL sizes, so if for example you've got a XXL helmet you can swap the liner and cheek pads to make it a L.
