Quite good, with some caveats

Pay a visit in advance - the bag is surprisingly spacious. With some Gequetsche even a 1.5L bottle fits into the larger of the two bags. Apart from this, can also mean an SLR plus lens without secondary problems tuck into the pocket.
From the splitting her man has two compartments on the front - one larger and one smaller. The strap (the part which rests at Diagonal wear on the chest) is also attached a small bag in which a smaller smart phone, keys or other should go out.
On the whole, therefore, five star, if not a little thing would be that bothers me personally.

I carry the bag like not even diagonally, but only loosely on the Schuler as you would wear a normal backpack on a belt. As a right-handed me the right hand side is therefore prefer. The backpack is so constructed that you can wear it just to the left (= viewed frontally the large backpack straps going from the top center to the bottom left). You can move to the right side that with a little skill, but the band is sitting so pretty loose, so you always have to follow suit.
Thus, there is for 2 star deduction.

If you want to wear the bag diagonally or on the left shoulder, it is perfect for. On the right side rather less.
