Stunt Puppy worked with dog walkers, runners and a very clever fabric developer to create the ultimate durable, lightweight portable water bowl. Made with revolutionary, patent-pending Nanopore Waterproof™ Membrane, the Nano Bowl™ truly punches well above its tiny weight. It's self-supporting even on uneven ground, folds down to the size of a handkerchief and attaches easily to leashes or belts for every on-the-go adventure. FDA-certified as food safe and chemical free, double-layered for water-tightness and durability. Great for dogs of all shapes and sizes! Machine washable, hypoallergenic and naturally antimicrobial.
