The Montane comes with a decent hood and has loops for glove attachments. The Montane Buffalo S6 and issue copies all have to be put over your head, which is a PITA. From memory Montane do a conventional style front zip jacket.
I thought I'd bung the Smock in but your right PITA - the Extreme jacket and Prisim jacket are in my post as you can see , the OP should look at a Keela Jacket (Multi cam ) with a Marino base layer as that's my combination these days , comfortable enough to wear in snow or rain while on the move with weight on your back but also warm enough to stop . No need to be putting kit on kit off as it does it all in one !
