If you open the bag, it basically consists of two compartments:
The ground where an elastic strap is available to the entire luggage to get again a little more compact.
The cover, which consists of a grid where you can stuff (like a tablet, or the Toiletttasche) pour in separately.
When packing I already noticed how much space you really have. I have really brought everything to pure clothing (+ spare), Toiletttasche, Chargers and tablet without any problems.
Once you into get everything you need, you can make the backpack with the zipper on the side and still attach the remaining 4 belts. One should best all first loosen completely, then click it and tighten finally sequentially. Thus, the piece of hand luggage is only compact properly.
At the airport in Munich I had the hand luggage do not even enter into the appropriate holder of EasyJet - I was waved through, so to speak directly. The same procedure is what happened at the airport in London.
Conclusion: I'm really happy with the product, since it is technically really are sophisticated (outside straps 4 + 1 inside elastic belt) and qualitatively nothing to complain about.
