Customer feedback describes useful carry-on storage, multiple compartments and under-seat fit, while also reporting mixed pump and USB charging function and stiff zips. These concerns matter if you rely on powered compression or need frequent access.

Frequently asked questions

Does the backpack include a pump?

What size is this backpack?

The size option says 40x30x20cm, and the dimensions field says 20D x 40W x 20H centimetres. Another feature description mentions 40x20x25, so check the selected listing and airline requirements before travelling.
