More Details: 1.8 liters might seem generous, but remember that one of the great things about a hydration system like this is that it lets you drink more and stay properly hydrated in the backwoods. Whether you're hiking, cycling, or mountaineering, we all tend to drink more when it's easily available and we don't have to stop. Any way you look at it, drinking a little more on the go is a good thing. Better hydration means less fatigue and a lower chance of certain injuries and strains. Fill your reservoir generously!
