The most important factor of staying safe on a day hike or multi-hour bike ride is hydration. Sure, staying on your feet and keeping clear of wildlife is also important, but keeping hydrated is something that you can control from the moment you lace up your shoes at the trailhead to when you are back to your car. Some days you might need a small pack for a short hike, while other adventures might have you hauling a pack that not only carries three liters of water comfortably, but also has enough storage to hold your helmet, tools and extra food. Read on to find out which hydration pack is right for you and your next epic adventure.
