[Model number: 55541] A compact business backpack with a slim body and concentrated storage capacity. The PVC processing applied to the polyester fabric of the main body enhances water resistance and durability, and the silicone coating adds smoothness and luster. The back compartment has an independent PC storage space that supports 13-inch class PCs. The inside uses a pile fabric that is less likely to scratch the surface of the PC. The interior of the main compartment is equipped with a "2-WAY Through Pocket" that allows you to take things in and out from both the side zipper of the main body and the main compartment. The inside uses moisture-absorbing and quick-drying mesh, which is convenient for storing folding umbrellas and plastic bottles. A utility pocket for storing small items is placed in the top part of the front, which tends to be a dead space in a normal backpack. The zipper pocket located on the lower right corner of the front is a "Quick Round Pocket" that makes it easy to take out small items even when you turn the backpack to the front of your body on the train. The back is a mesh cushion pad that provides excellent breathability and wearing comfort. Comes with shoulder & chest straps. Also equipped with a trolley bag setup function.
