Replying to What size bern macon summer helmet should i get????

with a beanie on, my head measures 60~61cm.

bern macon summer helmet comes in:
 
XL(59～60.5cm)
XXL(60.5～62cm)

Is there like a liner in the helmet i can remove so i can fit in the XL helmet?

thanks in advance +k

I would have posted thin in the gear forum but no one checks there and i sort of need an answer quickly. sorry guys.
