Nowadays, most commuters use backpacks and tote bags. Why not upgrade, though, to something a little — truthfully, a lot — more durable? Filson's 24 Hour Tin Cloth Briefcase is made how bags and briefcases used to be made: to last. Using 14-oz. 100% cotton Tin Cloth, which can be rewaxed when the water resistance wears off, for the exterior, Bridle leather for the handles and grip, nylon for the removable strap, dry Tin Cloth for the interior liner, and solid brass for the zippers, Filson made a bag designed for those doing business in both city offices and on rural worksites. Frankly, this thing can easily follow you wherever your work takes you.
