You’ve definitely seen work bags before. And you’ve probably even seen them with leather bottoms. But this carryall from Billykirk is made completely of leather. Revel in the luxuriousness that is the skin of a dead cow and revel in the fact that you’ll have the nicest secondary carry on in all of coach. Don’t let that brat in front of you spill his monster Jamba Juice on the floor because if your leather gets strawberry mango juice on it you're liable to blow up the entire plane with your rage alone.
