Alpine stars SR10 helmet

I’ve been talking to my local cycle gear today they told me they had my size and color of the Helmet in stock. 2XL WHITE CARBON SR10 (sadly doesn’t come in 3xl)

I’m almost certain it just from the factory this helmet probably will not fit my head , I currently wear a RF1400 3xl

Is there any mods such as buying thinner cheek pads for the helmet that could maybe help the fit?

I’m looking on the site and they sell 15mm cheek pads and cycle gear told me the stock ones are 25mm or 30mm.

Crown pads they also sell thinnest at 8mm

I believe my measurements of my head is around 65-66 and the 2XL SR10 is 63-64

Just looking for some help and answers because I am looking for a second helmet as New York summers in a matte black helmet will not feel good for my noggin
