For backpack: He only has one large compartment, not just for shoes. Bought it for backpacking, but it is tested when shopping. The belt feel from 18Kg filling something hard on. If you stay under 15Kg filling, it was very pleasant to wear. The extra side pockets there which provide for 50Eur per 10l extracting at Amazon, but were too expensive. At the processing can not be faulted. What could be improved would be a larger compartment in the back (ie a flat insertion option in the main compartment), unfortunately here not fit A4 papers into it. The load capacity is likely to be on an equal footing with the Bundeswerkampfrucksack.
Here I can say with a clear conscience, a strong buy recommendation.
