This bum bag is just perfect. The large front compartment is big enough to carry a folding dog water bowl, leads, poo bags, mobile phone, etc and even my raincoat when necessary. The 2 side pockets are wonderful for carrying your house keys in one and dog treats in the other. All compartments are zipped and the bag is waterproof. There is an additional zipped space at the back of the bag too. Well worth every penny. The photo shows my hubby wearing his. I almost forgot to mention the water bottle and holder at the front of the bum bag. Ideal for carrying water for you or the dog.
