Thanks for the replies, guys. The jacket is a REV'IT Tarmac Air Leather Jacket. Lots of armor, nice back protector, removable 'winter' liner, is perforated and vented (not that the latter matters when you're wearing a backpack).
I picked it up a couple months ago because I needed something more ventilated than my trusty Vanson. And looks now like Motorcycle Superstore has it on sale for $200 less than I paid for it!
