I use the waist bag mainly in the dog school. This one can attach the bag directly on the belt she does not wobble back and forth and makes the dog so tame. Approximately 400g diced cheese fit in. After about 3 months the opening stretch leiert something out, but it did not bother me - by the mutually overlapping slightly falls out nothing. The only drawback is the still very small extra pocket. The maximum occupancy is 2 Kotbeutel court if they have been previously folded well. And then it's also a bit fiddly to find out again.
