A hydration reservoir is not only convenient, it's important. The human body retains fluids better when they're taken slowly over time and passes them quickly when they're taken in large doses. A reservoir keeps hydration near hands and mouth, where you're more likely to use them. The Crux Reservoir has a wide mouth to make filling easy, even when already stuffed inside a pack. The bite valve has a full lockout feature that banishes leaks, a dream after picking your pack up out of a puddle to find the hose had been compressed under the pack load, and you're now out of water. It's an essential part of your backcountry kit.
