Expandable Backpack

Product details

More information

• About the product: A BANGE travel backpack offered in Black — Large and Black — Expandable, with a laptop compartment, external USB port and rear luggage-handle strap described.
• Expandable option: Black — Expandable is listed as changing from 36L to 55L through an expansion section. Confirm the actual dimensions in both configurations before planning your packing.
• Large option: Black — Large is described as a fixed-capacity choice. Its volume and dimensions are not stated; do not assume it has the same capacity or internal layout as the expandable option.
• Laptop fit: A fit up to 15.6 inches is claimed, but sleeve measurements are not supplied. Compare your device's physical dimensions, including any case, with the actual compartment.
• Travel organisation: Pack heavier items close to the back, protect the bag from sharp edges and close zips without forcing them. Check the packed profile before travel.
• USB connection: The listed external port is a pass-through connection, not a built-in power supply. A compatible power bank is needed and is not included.
• Trolley use: The rear strap is described for placing over a suitable suitcase handle. Balance the load and keep hold of the suitcase until stable.
• Care: Follow the delivered care label and dry fully before storage. Machine-washing suitability is not confirmed.
