The size is smaller than, for example, in the models of Delaware.
Had this bag in his hand, while I was looking for a bag for Canon EOS 100D + 18-55m IS STM kit lens. For this combination, the bag is a bit too small. Man kan they close, but I can not imagine that the strong pressure in the coating of the loop over the nose or the lens is good for precision mechanics permanently me. Have therefore opted for size L / LARGE, which fits perfectly.
