Can you add armor to a jacket?

I have an old Schott Perfecto that my Dad used to own, which I plan on using as a riding jacket when I buy a bike. Thing is, it's only leather, with no armor protection (that I know of) - so I'd like to add my own. Is this a very difficult task, or can I just sow in a couple pockets on the inside back and slip in some armor? via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/ey1zq9/can_you_add_armor_to_a_jacket/?utm_source=ifttt
