Water bottles are a necessary investment when going on a hike, and one that is well worth it. They will not only keep you hydrated but can be used as storage when you run out of water. Many of the water bottles on our list are below $20.00 and are still fantastic water bottles. It is not the cost but the features and the materials they are made of that matter most. Hiking without a water bottle is a risky move, so hopefully, you have found the perfect water bottle that will be best for you and your hiking style.
