The Flat Head sizing help

[Boots.and.brews]

Hi, I'm looking at the flat head single riders and double riders jacket and determining what size to potentially order. My chest is roughly 43" and shoulders 18".

Thanks!

You will need something bigger than 42. Thats as much as I can help. I could just squeeze into the 42 with a 41 inch chest.
