With its waterproof sector fabric, this backpack is ready for heavy use with its padded 15.6-inch laptop compartment and multiple zip pockets. Its power-bank pocket, pen holder and card-phone slot provide order, its side pocket makes room for bottle and umbrella, and the air-circulating back cushion gives comfort.

With domestic production quality, it is an ideal promotional product for sector institutions, tech companies and corporate-staff gifts. It represents the institutional identity strongly and functionally by turning its wide surface into a brand with logo printing.
