Owala
Owala's selling point is the FreeSip lid, and that lid is where the plastic lives: the spout, the integrated straw, and the push-button cap are all BPA-free Tritan, with silicone gaskets sealing the works. The steel body keeps your drink cold, but you sip through plastic either way you drink - straw or spout. It is a steel bottle whose entire drink-contact mechanism is plastic.
How clear are their specs?
Owala labels the plastic parts BPA-free Tritan and sells replacement lids and straws, so the materials are discoverable, but the marketing leans on "BPA-free" rather than acknowledging the sip path is plastic.
Lead testing disclosure
Owala's FAQ and a blog post ("Owala Water Bottles Will Always Be Lead Free") assert lead-free status and mention "lead-free solder," but neither names a third-party lab nor cites actual test numbers or detection limits - a bare claim, not disclosure. Independent XRF testing (Lead Safe Mama) of an Owala bottle found it lead-free with trace cadmium in the silicone, but that testing lives on the tester's own site; Owala does not publish, host, or link to it.
