I'm trying to find a new 3-in-1 Columbia coat for my father. The problem is he will only wear the 3-in-1 coats if the outer shell has a dual zipper where he can open the jacket from the bottom for driving purposes. Does the Columbia Air Chamber Parka have a dual zipper on the outer shell like I just described?
