This is a great bag. I use it with the Roamer bungee leash. (Excellent leash by the way). Very easy to attach and carries all of your essentials. Phone, treats, cash and any other small necessities. The poop bag striker for easily opening the bags is an excellent feature. Then just hang the bag from the exterior cinch loop so it’s not hanging out with your “human” valuables. Perfect for hands free dog time!
