I thought you all might like to see my custom size 38 Aero Board Racer since it features some uncommon selections. For maximum comfort and mobility I opted for battered steerhide and added shoulder gussets. It feels like I'm cheating with respect to breaking in the jacket! Other options include a T back with no kidney panels, zipper-less hand warmers, the Aero "Rock n Roll label", a left side vertical interior pocket, and adding an inch in both body and sleeve length. For lining I chose olive cotton drill with olive sateen for the sleeves. The fit is perfect and it was such a pleasure to deal with Carrie at Thurston Bros during the entire process.
