ALVABABY wet/dry bags are made from waterproof 100% polyester and come in three sizes: large, medium, and small. These bags are designed to hold dirty cloth diapers, swimsuits, clothes, gym clothes, and more. Each bag features two zippered compartments to keep wet and dry items separate, with a 'wet' section that is sewn and sealed to prevent leaks. The bags come with handles for easy carrying or attaching to a diaper bag or stroller.
