Dry bags are waterproof bags designed to keep contents completely dry in wet conditions. They are made of durable waterproof materials such as PVC or nylon and are commonly used for activities such as kayaking, boating, hiking or camping. Dry bags protect gear such as clothing, electronics, and food from rain, splashes, or complete submersion in water, making them a must-have for outdoor and water adventures.

Hydration bag is a backpack or undershirt with a built-in water reservoir (also known as a bladder) and a hose for hands-free drinking. Popular with hikers, cyclists, runners, and outdoor athletes, these hydration packs allow users to stay hydrated without interruption. They are lightweight, comfortable, and often hold small essentials like snacks, keys, or tools.
