Light(er) weight peacoats?

I absolutely love my US navy peacoat I got issued way back when. But while the Northern California coast is cold....its not 20oz Melton wool + insulated lining type of cold. So if anyone has a wool or wool blend peacoat that reasonably looks close I'd appreciate it.

I've seen a few close options, but they either tend to be in grey or have dumb extra details like too long, epaulets or extra a-historical pockets.
