I've heard of people being called tool bags but I've never actually seen a "Tool Bag". Thanks to The San Fernando Valley Mercantile Co. I know what one actually looks like. This stylish bag packs some serious durability you probably could actually throw some tools in the mofo but I'm thinking using it for a carry-on bag is probably what most of us non construction workers will end up doing. Based on a Bell Systems repairman's bag The San Fernando Valley Mercantile Co. has reconstructed this classic using cotton green duck canvas, top grain leather on all of the straps (yes there is a shoulder strap too), and antique nickel rivets to finish it off. Grab yours and join a union.
