What do you call a jacket like this?

Not as an insult but "blue collar."

I have one that looks very similar. A Dickies lined mechanic's jacket. They call it the Eisenhower Nazy blue, bronze zipper. In the pic, his looks worn in. You can get them at Sears.

it's almost like a harrington but no elastic bands

A mechanic's jacket.

I have one like that and I call it a "worker's jacket." I think I made that up myself though to distinguish from "Bowie jacket" and "the peacoat" which are also black.

edit: as per oscar rowsdower's post, I'm gonna call it a "mechanic's jacket" now.

WTF its called a golf jacket folks.
