Not sure I'm Harrison Ford enough, but I forgot about Wested. Quality products at least.
Carhartt has a few durable and functional rain jackets that seemed of decent quality. Much better than the typical thin polyester/rubber.
I actually just like the way that jacket fits, with a couple of modifications; and it looks good anywhere. Style doesn't get more timeless than that.
The large collar is nice for rain and chilly wind. I'll probably end up having another one made at some point, and putting a snap up there or something so I can keep it closed; or just having some mods done when I send it for a new liner.
They will absolutely go full custom. They just do a lot of movie stuff and people are attracted to that, so that's where the marketing focus is. The guy that runs the joint is one bad motherfucker, and very nice. He's the kind of guy everyone wants to know. Everyone is, and their stuff is made right there, by hand (obviously with the aid of a few sewing machines), and beautifully.
The prices are extremely good, as well. Quite often you'll pay more for Chinese crap.
I think you'd be happy with Filson coats, or Wested, if you go leather. They'll use other materials, but obviously that's their focus. Hell, they'll make you gloves from scratch if you like.
Filson sizing can be a bit odd for people of my shape. I'm short, but I'm a triangle. I have trouble everywhere finding stuff that fits right, but they can run larger or smaller depending upon whether it's an outer layer or inner. Their stuff is designed specifically to be worn over insulation, which is the way it should be. Don't think you'll toss it over a T shirt and be ready for winter.
Wested sizing... Go get measured for a tailored suit first. It's going to fit precisely how you want it to.
Check out my man with a smoke in front and booze in the back, ready for action. Sixteen tons of confidence. The coat I had made that day was ready the next morning, and he even dropped me off at a bed and breakfast, as I'd walked there.
Cheers,
