What to know before buying

Listing details to confirm

The listing is inconsistent about composition and storage: details list Nylon, while feature text says 60% Nylon and 40% Polyester. It also states seven compartments and seven zippered compartments, but separately describes four front zip pockets plus a main, laptop and bottle storage. Confirm the construction and pocket layout for the selected version. Water-repellent does not establish that the bag is waterproof.
