Frequently Asked Questions
Q: What laptop size fits in this backpack?
A: The dedicated laptop sleeve fits notebooks up to 17 inches. Please compare your device's dimensions with the compartment size before purchasing to confirm fit.
Q: How does the expandable design work?
A: The main compartment can be expanded by unzipping a hidden expansion zipper, increasing the depth from 18 cm to 28 cm and the total capacity to 39 liters. This allows the bag to adapt between everyday carry and heavier travel loads.
Q: Does the USB charging port come with a power bank?
A: No. The USB port is a built-in pass-through port. You will need to place your own power bank inside the bag and connect it to the internal cable to use the external port.
Q: What is the wet/dry separation compartment for?
A: The wet/dry separation compartment allows you to store damp items (such as gym clothes, a wet umbrella, or toiletries) separately from your dry gear, keeping the rest of your bag contents clean and dry.
Q: Is this backpack water-resistant?
A: The Oxford exterior offers a degree of resistance against light rain and splashes. It is not designed for heavy rain or submersion. We recommend keeping it away from prolonged moisture exposure.
