Waterproof and water-resistant are two terms that are often confused and used interchangeably, but they are actually two distinct terms. Waterproof means that an item is completely impervious to water. This means that the item will not be damaged or otherwise affected when submerged in water. Water-resistant, on the other hand, means that an item is able to resist water to some degree, but not completely. It is designed to withstand exposure to water for a certain amount of time, but will eventually be damaged if exposed for too long.
