Lowepro great quality. Since there is nothing to complain about. Many thoughtful solutions in order to accommodate the photographic equipment can. However, I came out with a Backpack assume that there's a little place for trekking utensils. Unfortunately, there is no extra pocket for it. One can of course accommodate the main compartment with the photographic equipment, but is not comfortable. The extra pocket for the notebook is a little too narrow for my taste. Enough perhaps for an Apple Airbook. For larger notebooks, it is difficult and it's quite a Stopferei. Maybe it's better in the larger Pro Trekker versions. Bin me then but not sure if that still go through as hand luggage, as it already reached its maximum size.
