After receiving several samples to try out, this one was the clear "winner". It's slim enough to put in the little side pouches many backpacks have on the side, but tall enough to hold a lot of water. The size of it, the carrying clip, and the design of the bottle/spout were great; anyone who hates it when the water pours out too quickly will appreciate this design, as there is a built in bump that helps control the water flow. The imprint also looks great - thank you!
