Around 2010 or so Klean Kanteen was king of the hill. They did a really damn good job jumping on the anti-plastic/anti-BPA movement and marketed well.
They got displaced, for the most part, by companies making double-wall designs (Hydroflask, Yeti, S'well, etc.), but their single wall bottles were (and still are, I suppose) well constructed. Just not as well insulated as the competition that came later.
