If you want one of the largest, lightest and best value cabin/hand luggage bags on the market then your looking at it. As we all know flying with hand-luggage can be a struggle these days with so many airlines using different sizes and weight allowances. The bag you are looking at will work (even when packed full ) for your three main budget airlines; Ryanair, Easyjet and BMI baby. It works well for these airlines because it measures 55cm x 34cm x 19cm which is very close to, but still smaller than the sizes these airlines work to. In the final picture you will see one of these bags inside a hand luggage cage that has been made to the sizes 55cm x 40cm x 20cm. As I'm sure you'll already know this is the size a lot of budget airlines work to. As you can see not only does it fit inside the cage, but it also almost fills the cage, meaning your able to get the maximum amount onto the plane. The bags capacity is approx 35 lts The other important issue to address is weight, now the majority of wheeled hand luggage bags (trolley cases, wheeled holdalls and wheeled backpacks ) weigh 2.5 kgs -3.5 kgs when empty. The bag your looking at here weighs less than 1kg ( 0.8 kgs to be exact ). The final thing to say about this bag is that due to its soft nature you are able to fold it down so it will store very easily.
