What is the purpose of a 'waterproof case'?

The purpose of a waterproof case is primarily to keep items dry. These cases are designed to prevent moisture from getting inside, which is crucial when storing electronics, documents, or other sensitive items that can be damaged by water. The materials used in waterproof cases are typically resistant to water infiltration, ensuring that whatever is inside remains protected from splashes, rain, or submersion. This functionality is vital for adventurers and outdoor enthusiasts, as it allows them to carry essential gear without the risk of water damage.

While there are other products that can offer flotation or assistance in kayaking, the fundamental role of a waterproof case centers around safeguarding contents from water exposure.
