I recently stopped using hydration reservoirs on a regular basis due to the difficulty in cleaning them. Unfortunately, I found that when I did not use a reservoir, I was drinking less water. I also found it annoying to carry several bottles when I needed to carry a large amount of water. With some recent battles with cramping, I decided that I should find a reversible hydration reservoir, which I believed, would make cleaning, drying and staying hydrated much easier. In my search to find one, I ran across a company that I had never heard of: GEIGERRIG.
Here are some photos of their gear, as well as a link to my full review:
