Last winter here in Michigan, we saw temperatures as low as -15F. If I were to be out in that in Fedora Lounge approved apparel, what would it be? I have my insulated Arcteryx jacket that I wear for more athletic wear, however what is a A-2 equivalent of this? I have a Crescent Down Works vest and am tempted to pick up one of their parkas or pullovers. Just want to keep my closet homogeneous, if that makes sense. Edit: I have a B-6 arriving today.
