Water-resistant and waterproof are terms used to describe how well a material or product can resist water. The main difference between the two is the level of protection they offer against water.
Water-resistant means that the material or product can resist the penetration of water to some degree, but not entirely. It can withstand light rain or water splashes for a short time, but prolonged exposure to water or heavy rain can seep through the material and damage the contents of the item.
Waterproof, on the other hand, means that the material or product is entirely impervious to water and will not allow any water to penetrate. It is designed to withstand heavy rain, submersion in water, or other harsh weather conditions without allowing any water to seep through.
