I've spent the past years in tote world. I've had countless discussions about the merits and drawbacks of sizes, function and weights.
This is the result of my field work. Large enough to carry around your things, small enough that you can't overload it (sound familar? Bueller?)
Dimensions 13" height, 12 1/2" width, 2" depth. Inside pocket, 10" drop latigo handles. Open top, unlined.
Made from a stunning black nubuck skin with gorgeous sheen and nice weight, this bag will last forever. Clean with a suede brush
Made at my SF workshop
