Nalgene bottles
… made from Polycarbonate
here is a modern variant with Eastman Tritan plastic (same material as the new huel shakers), which is physically more stable than Polycarbonate, but also emits synthetic estrogen:
According to internal Eastman documents, in 2008 Eastman signed a two-year contract with Sciences International, another product defense firm that had played a key role in the tobacco industry’s scientific misinformation campaign. On Sciences’ advice, Eastman then commissioned a study that used computer modeling to predict whether a substance contains synthetic estrogens, based on its chemical structure. The model suggested that one of Tritan’s ingredients—triphenyl phosphate, or TPP—was more estrogenic than BPA.
