To create the best hydration pack for running review possible, we researched countless models and consumer reviews, used our past experience, and consulted veteran runners to select an assortment of packs. We purchased them all from online retailers, filled them, strapped them on, and hit the trails. We covered hundreds of miles with the objective of learning the strengths and weaknesses of each pack — information we pass on to you. Below are the criteria and performance metrics we used to rate each product.
Over the trails and through the mountains to grandmother's house we go… We loaded these packs up and headed out into the desert alpine of Arizona and the Sierra Nevada in California. From cold nights to intensely hot days, we tried to tease out which packs were bouncy, chaffed, easily adjusted, soft to the touch, created pressure points, and on and on. The only way to test comfort is to wear the pack and put in the miles while having an awareness of what the pack is doing and the extent of how adjustments can help. Having access to a huge pile of other vests for comparison helps in this hunt. After all, if you don't have anything to compare to how would you know?
Features and Design
Each pack we tested was like a unique snowflake. They all had their take on what a hydration pack for running should be and what it should offer even when their goal was ultimately the same one. We looked over the packs, put them side to side, and tested the features out on the trail. The packs for 2019 ranged from those that offered the very basic essentials to packs that had probably more features than we would actually utilize, like ice axe storage.
Rating and testing the hydration system was a bit tricky, as all vests, even those with similar hydration systems, are quite different. They all seemed to have a niche where they would perform better than others. That being said, things like capacity, ease of filling, and leakage were all important factors that we examined. Other issues like hose management for packs with hydration reservoirs, and how difficult the soft flasks were to stuff was also considered in the overall hydration system rating and testing.
We gathered up a light but versatile kit of equipment to pack along for every run. We used the exact same kit for each one of the vests that we tested. Our storage capacity results show both the storage beyond the basic kit as well as how easily packed and organized the equipment was.
We paid special attention to the placement, size, amount, closure systems, and overall volume of the pockets on each hydration pack. The score in this category is an amalgamation of these elements that ultimately shows how useful the pockets on the pack were. Some packs had tons of pockets but had so much overlap in the space the pockets used they just weren't useful. As strictly giving higher scores for more pockets would be ridiculous, we scrutinized the efficiency of each pocket and asked the question, is this pocket necessary to help me accomplish my running goal?
Ideally, a hydration pack for running will be lightweight and efficient. Being the lightest ever isn't necessarily critical, but it is important that these packs be built with an eye towards efficiency and weight. As such, we put each on the scale straight from the shipping box with no water on board.
