Very clever design and a very convenient size. This is just enough water for a good walk, not a long hike, but a long walk or playtime. The strap is wide, soft and adjusts easily. Love the checkerboard black and white design which is the same as the Finish flag of a NASCAR race. The light weight container secures from leaks while being easy to fill. There’s an attached dish which stays completely out of the way and doesn’t add weight. There’s also a poop bag compartment cleverly built in. It’s the, most convenient pet water container I’ve found because of its compact, lightweight, useful design.
