My husband prefers this lunch tote to the upright one he's been using because of the size and shape. The measurements, similar to metal lunchboxes, allow him to place different-sized tupperware is a variety of packing methods. The padding and the attachment clip-buckle prevent him from damaging or dropping his lunch when carrying multiple items from his car to the office in the mornings. However, there is no insulation, which I find ridiculous.
