I've been using the same clip-on treat pouch for 5 years and wanted an upgrade! This fanny pack has a very large zippered main pocket seemingly meant for human things like a phone and credit card. The front treat pocket is very small and not secured by a magnetic closure or anything - it was too small to easily get a hand in to access treats, and I was worried about how secure it would be with small training treats that would just slip out. There is a poop bag dispenser that works with rolls, and there is also a small back mesh pocket.
I like the bag - it's stylish and sleek and I wanted a fanny pack style, but the pocket configuration doesn't really work for me. I use dog bags with tie handles, which don't come in rolls, so the bag dispenser part is useless (I use the back mesh, which isn't quite big enough). I wanted more room for treats than the designated treat space, so I end up using the main pocket, which means there's no place to put my phone. Wish the front treat pocket was larger, the main pocket smaller, and the mesh part taller to hold things more securely.
