Kono Anti-Theft Cabin Backpack 40×30×20cm
Kono Anti-Theft Cabin Backpack 40×30×20cm
A cabin backpack with the pockets where a pickpocket cannot reach them and a main compartment that opens flat. It also has a wet and dry divider, which matters more than it sounds when you are packing a swimming costume on the last morning.

On the anti-theft design
The useful pockets sit against your back or under a flap rather than on the outside. That makes casual theft harder. It is not a security product, it has no lock, and a determined thief with a knife is a different problem. We would rather describe it accurately than sell it as something it is not.
On airline fit
At 40×30×20cm this is exactly the size Ryanair publishes for the free small personal bag that goes under the seat (checked on Ryanair's help centre, 16 September 2026), and it is inside easyJet's free under-seat size. No margin on Ryanair's sizer, so it fits only while it is not overpacked. Check your airline's current published allowance before you fly.
One-year manufacturer's warranty on this bag.
The measurements and materials above are the manufacturer's, not our own. We have not measured a sample ourselves, and we would rather say so than imply otherwise.
