A bag you'll forget you're carrying

"I hate running with a hydration pack, but since I run trails, sometimes you just have to push through it. I just went on a 2-hour-and-50-minute run, and the pack never got in my way. Everything is perfectly accessible, and I'm very happy with my purchase. Plus, the price is truly unbeatable!"
