I just placed an order for a custom Thunderbird and I took the opportunity to snap a few pics of the fit jacket while I had it in my possession. For what it's worth, the Comp Weight leather on the fit jacket was glorious. It felt a bit softer than my Comp Weight Mercury circa 2017. But then I'm convinced that the leather on my Mercury came from a particular stiff and unforgiving batch of Comp Weight leather. haha! By comparison, that Thunderbird gave me the impression that it wouldn't take nearly as much effort to break in. We shall see. It's gonna be a very long summer. Can't wait! Fun fact: The Thunderbird is fully insulated, both body and sleeves. I didn't know Vanson did that on any model.
