Manufacturers of ATV rear passenger seats really understand that many people need extra protection for their storage boxes. Everyone wants to protect their belongings, but everywhere you need to know the measure and whether the material’s capabilities will allow it not to let a large amount of water through. In most cases, when manufacturers write about the water resistance of the material, this is true, but if you drop the storage box, for example, into a river or any other body of water, then most likely the water will still leak inside.
