The range of trail running backpacks is large, starting with compact running vests, to small hydration packs, all the way to all-rounders for mountain runs with a volume of 9 liters or more. In addition, there are also hipbelts, waist packs, and running belts that usually only hold one bottle and feature a small pocket for a key or mobile phone. Which model is best-suited for you depend in particular on the trail or the races that you like to run. On your after-work loop around the reservoir a running belt is perhaps plenty, but for an ultra in the mountains you certainly need a significantly larger backpack to fit everything in that you need. Whatever you have planned, at DYNAFIT you will find backpacks with all different volumes and features. Meaning you’ll be geared up for every running adventure.
