This stow-and-go bag is made from the same material as dry bags, but with the intent of keeping water in rather than out. A ribbed spout and two handles make pouring easy, the flat base allows for hands-free refills, and a waterproof zipper keeps water contained while you’re carrying it around the garden. Doubles as a tote for harvesting or hitting the farmer’s market — and it rolls up when you’re done.
