Because the old one looked like this http://toj-gallery.com/main.php?g2_itemId=6598. It's not cold enough to wear my jackets zipped up most of the time in LA, and I don't like how floppy the old one looked unzipped.
Graphite grey CM next to black lamb MDR. Graphite is a really good description of it. Personally I am happy with the graphite calf, really nice stuff.
I kind of wish there was another style of jacket I wanted so I could order the blood red calf. Perhaps it's fortunate there isn't though.
