Love this bum bag. It has so many different sections / compartments, that you can not help, but to be organised! No more digging through the bum bag for the house key after taking the dog for a walk, as the keys have their own compartment. Their is a section for the dog water bottle, another for the spare 'doggy do' bags and another for the dog treats. There are various size compartment for various items. This bum bag is not just useful but very practical.
