After I was forced to switch to a broken leg and crutches backpack I bought the Cabin Max because of the many good reviews. At first I was excited. The backpack is super light, so that even with the stringent controls on Ryanair the 10 kg limit is difficult to achieve, despite notebook, camera, magazines and books in their luggage.
Unfortunately, after 2 flights the fun was over, because the seams broke at the top and was open for a length of 20 cm of the backpack. Too bad, luckily I can take my good old travel bag back, because the crutches now dust in the attic in front of them.
Conclusion: A little more care in processing would have made the Cabin Max the perfect companion for air travel. Due to the opening seams just a star. For two-time use then too expensive.
