Troop London TPB003 Business Expandable Laptop Backpack

The TPB003 adds one feature that transforms a good laptop backpack into a great travel one — an expandable zip function that increases the bag's capacity when you need it and keeps it compact when you don't. Built from high-density 1680D polyester with a water-resistant and scratch-resistant finish, it combines daily commuter practicality with the flexibility to handle overnight trips, gym sessions, or days when you're simply carrying more.

All the Business Collection essentials are here: a padded 15.6" laptop compartment with elastic securing band, an anti-shake back panel and memory foam padded shoulder straps for all-day comfort, a built-in USB-C charging port, a hidden security zip pocket on the back panel for passport and wallet, and a luggage strap for travel. Inside, 2 open-top pockets, 3 card pockets, and 3 pen holders keep everything in its place, alongside an internal zip pocket and a spacious main compartment.
The expandable zip at the base of the bag — the defining feature of the TPB003 — gives you significantly more room when you need to carry extra without permanently enlarging the bag's profile.
