>>2400202Nalgene's plastic bottles are made in the US. GIven I can't find any provenance for the Helikon Tex bottle, I'd guess it's made in China as a copy of the Nalgene design. Nalgene offers a lifetime warranty on their products. I don't know what Helikon Tex's bottles are like.
Also, the Helikon Tex bottle apparently comes with one of these. Which, while I favor the Nalgene bottles for the support, is really neat. They do make these for the Nalgenes, but they're something you need to buy separately.
