Where can I buy a black leather coat?

You might try Leather.com

It’s the San Diego Leather Jacket Company. They’ve been in business for eons and specialize in cow leather (as opposed to deer or goat or whatever else) and their catalogue includes fashion items for every genre and functional items for every profession. Lots of law enforcement people (particularly motorcycle cops) get their stuff through these guys.

I happened to pick up a jacket that was custom-ordered by someone else but never picked up. It cost me <$100 off the clearance rack. That was in 1992 and it’s still doing a great job for me today. I replaced the zipper once, but the skin looks brand new, even though I’ve been commuting by motorcycle with it just about every weekday.

–G!
