I never realized how strong the taste of plastic was in my Nalgene bottles until I tried a stainless steel bottle. Granted, Nalgene is slightly better than some other kinds of plastic bottles, but it still pales in comparison to steel. I have both a Green Feet and Kleen Kanteen bottle and the water tastes so much more...well...clean! I'm never going back.
