Stable hydration pack for long runs
I bought this pack for marathon training and have liked it for that purpose. Its best feature is probably the stable ride. I have found it comfortable over long runs, and the side compression straps allow me to keep it stable as the volume decreases (from drinking). It also has plenty of room for keys, a few gels, and a light windbreaker. The tube is adjustable (just cut to length), easy to drink from, and doesn't drip. Overall, this is a good running hydration solution.
