30L–40L Expandable Travel Backpack

This black travel backpack uses an expansion zipper to change the supplier-listed capacity from approximately 30 L to 40 L. It combines a suitcase-style main compartment, separate laptop storage and smaller organizer pockets for commuting, business trips and short travel.

Storage and Travel Features

Expansion zipper increases the listed depth from about 19 cm to 24 cm
Main compartment for clothing and travel items
Separate section listed for laptops up to 17.3 inches
Middle and front zipper pockets for documents and accessories
Side pockets for suitable bottles or other compact items
Lay-flat opening for easier packing
Rear luggage sleeve for use with a rolling suitcase
External USB fitting with an internal cable connection

The USB fitting is a cable pass-through only; a power bank and charging cable are not listed as included. Laptop dimensions vary, so the intended device should be checked against an approved sample rather than relying on the diagonal screen size alone.

Reference size	Approximately 31 × 19 × 50 cm before expansion
Expanded depth	Approximately 24 cm
Listed weight	Approximately 1.25 kg

30L or 40L? Three Checks Before You Order

Start with the unexpanded 30L reference layout if your laptop, charger and clothing fit without forcing the zip. Open the expansion zip when you need extra depth for a thicker packing cube or an extra layer. The two capacities are reference figures for the same expandable travel backpack.

Pack the same kit in both settings. Lay the bag flat and pack the intended clothes, laptop and charger. Close it in the 30L setting, then open the expansion zip and repeat with the extra item that prompted the larger size. Check whether the main zip runs freely around the corners in both settings.
Measure the packed bag, not just the empty shell. The listed depth is about 19 cm before expansion and 24 cm after expansion. Check the fullest point with the kit packed. If cabin travel matters, compare the loaded dimensions with the allowance for the intended flight; neither setting guarantees acceptance.
Check whether the extra depth blocks laptop access. With the bag fully packed, try removing the laptop from its separate section without unpacking the clothing. If the device has a case, include it in the fit test rather than relying on screen size alone.

When you request a sample, send the packing-cube dimensions, the laptop dimensions and the maximum packed depth you need.
