Whether you're hitting the trail with your own two feet or on top of your trusty bike, the ALPS Mountaineering Hydro Trail Backpack is guaranteed to make your day's adventure a success. A suspended mesh backpanel, contoured shoulder straps, and both a waist and sternum strap all work together to provide a stable, comfy carry system that won't jostle too much, while 17-liters of space within neatly organize your lunch, tools, extra layers, and camera. Then, arguably the star of the show, the three-liter ALPS hydration reservoir and its easy-to-use drinking tube (that clips to your shoulder strap) keeps water right where you want it when you need a break. An included rain cover helps protect your gear from the elements, and reflective details throughout boost your visibility on low-light adventures.
