Stainless steel bottles are as chemically safe as you can get, and don't absorb odors and bacteria like so many plastic bottles. The insulated steel bottles will keep your water cold for longer than you can ride. I've been using stainless steel bottles for years.
I do have to admit that the Camelbak Big Chill Podium bottles are breaking me down though. They are awesome bottles.
