There is no luck involved in designing and building leather backpacks, wallets, satchels or briefcases to last 100 years. Each leather bag and wallet was made with the strongest and densest leather on the market, lining that's even stronger than the cowskin, the strongest thread we could buy and the highest tensile strength hardware on any leather backpack, briefcase, satchel or duffle bag in the world. They'll fight over it when you're dead.
