Hydration systems are devices designed to help individuals drink water easily while on the move. They typically consist of a water reservoir, a tube, and a bite valve, allowing users to sip water without stopping their activities. These systems are popular among outdoor enthusiasts, such as hikers and cyclists, as they provide convenient access to hydration. Many hydration systems are made from lightweight, durable materials and can be integrated into backpacks or worn as vests. They are essential for maintaining proper hydration during physical activities, especially in hot or dry conditions, where fluid loss can occur rapidly.
