I used to prefer the smock type, but recently i have swayed over to full button, reasons, the smock type heavier material,tighter fit(well to me) harder to get on and off,feels more restrictive, were as the full button(bit of pain to remove all buttons when your modding) but after is lighter material but still tough,more comfy, same size pockets/hood,packs smaller,still was wind proof all my personnel opinions. oh and i only open a couple of buttons and pull it over my head,but its does seem to come on and off easier probably down to fabric weight.
