Hello, first post here. Been doing a lot of reading and searching but didn't find the exact answer. I'm in the process of getting a custom jacket from us authentic. I'm prob going to start with the sportster and make the following changes: A2 collar, storm flap for zipper, no zipper on pockets, and inch or two longer. I've got some leather samples coming but wanted some input. I'm hoping someone has some pics of the vintage horsehide. Also, would horsehide be too stiff for an everyday wear or should I have it made in something else? How warm are these jackets for winter. I live in Minnesota so it gets REALLY cold up here. They can add either a fixed thinsulate lining or removable wool lining. I appreciate any thoughts, concerns or other suggestions. Thanks for all the help.
