For a sport as active and demanding as trail running, you’ll want a smaller rucksack with a close fit to your body, maximum breathability and great features to ensure an easy time while running. Look out for features such as hydration pack compatibility, accessible water bottle holders, and handy zips or straps. A rucksack which moves about on your back as you run will get annoying very quickly, and if you plan to run for a long distance, it could even cause rubbing and blisters.
