I bought two bottles of Smart Water solely because they are good, heavy duty plastic bottles that will fit in my vehicles' cupholders and I can refill them from my Britta filter. I looked long and hard for clear plastic water bottles that would meet this purpose and they are all either too wide on the bottom, not clear, or have some sort of fancy straw or spigot top. The only problem with this solution is that now people might think I'm dumb enough to buy Smart Water.
