I haven't had a request for jackets, but they could be made with either CB.com logo embroidered on them. I can get pretty much anything. It's just a matter of cost since they'll be one off items.
Send me an example of the jacket style you would be looking for and I can see what's available from my embroidery source.
Not sure what they have on Extreme Chevy (couldn't find a site by that name) but these wouldn't be a big logo on the back or anything. Just small embroidered logo on the front pocket area.
