That looks an awful lot like a Belstaff “long way up down” jacket as worn by one of Ewan or Charlie for their Long Way Up series. I’ve got one and love it. Not much of a collar is a major redeeming feature for me as my pet hate is wearing two or three layers each with a collar each of which just gets in the way of the other. Nice and warm and great on and off the bike. Good pockets too.
GLWTS.
