What to know before buying

Listing details to confirm

Listing details are inconsistent: it describes 10 compartments, 5 pockets and 3 sections, while feature text says 10+ pockets and a product graphic describes two main compartments. Materials are also described as nylon in one detail and water-resistant polyester fabric elsewhere. Check the selected listing for the precise organisation and material details. The claimed fit for laptops up to 17 inches should be checked against the device’s dimensions, as the listed laptop compartment measures 40 x 27 x 5 cm.
