The reviewer appreciates the front compartment’s defined areas and improved organization, while finding its diagonal layout less intuitive for quick drop-ins. The reviewer describes the closed-loop harness as comfortable, with adjusted strap length staying organized and no excess webbing dangling afterward. A raised, dimensional mesh pocket keeps cables, AirPods, and other small technology accessories separated from the main cavity.
The reviewer says the padded sleeve fits tablets up to 8.3 inches and can also serve as a quick-access phone pocket. The reviewer notes that the structured sling retains bulk when lightly packed, leaving unused volume with only a phone, wallet, and keys.
