This is a Barbour quilted jacket. I bought one before Christmas. It keeps the cold out in the morning but isn't so heavy that you swelter when going home on the Victoria Line. I'd seen smart Spanish-looking men wearing them. I saw Dave, the transport manager in our building, wearing one and he said he'd recommend them.
Hence I got one. Since then I've hardly worn anything else. Problem is I'm clearly not the only one. There are increasing numbers of them out there in the world. There are quite enough of them indoors as well. In a fashion wave which is unprecedented in our family, my son, his girlfriend and now one of my daughters have also bought them. Theirs are not identical but they're close enough that if we all go out together we look like a sponsored shooting party. Now the other daughter says she wants one too. Enough, I think.
