Unless you’re among the lucky few living in places like Madison, Malibu, Boulder, or Asheville, you probably don’t have picture-perfect nature trails a few steps from your front door. So for the rest of us, our daily routes are an untamed cluster of pavement, crosswalks, and traffic. Thankfully, TETON Sports has created the TrailRunner 2 Hydration Backpack for every type of outdoor enthusiast: the outdoor fitness nut who craves running through the serene tree-lined wilderness, carving banked corners on two wheels or paddling across waves and the urban adventurer who often settles for neighborhoods, distracted drivers, and the occasional stray dog.
