YETI
YETI builds the steel body up as the story, and the steel is genuinely heavy-duty, but every lid the drink flows through is plastic. The MagSlider tumbler lid is clear BPA-free Tritan with a plastic magnetic slider you sip over; the kids Straw Cap and adult straw/chug caps are BPA-free plastic too. "All YETI Drinkware is BPA-free" is the brand's line - a chemical claim, not a plastic-free one. The premium price buys durable steel, not a plastic-free drink path.
How clear are their specs?
YETI states lids are BPA-free and some retailer listings name Tritan, but the brand's own copy sticks to "BPA-free" and does not dwell on the plastic sip surface.
Lead testing disclosure
YETI maintains a public "Manufacturing FAQ" page that directly acknowledges its Rambler drinkware uses a lead-containing sealing bead/dot to achieve vacuum insulation, fully encapsulated under the base and outside the drink path. It states products are "frequently tested at a 3rd party accredited lab" per COE Resolution CM/RES(2013)9, cites a specific detection limit (<0.002 mg/kg / ppm lead, not detected on accessible surfaces), and references compliance testing against US FDA lead standards, CA Prop 65, and EU REACH/SVHC. This is a substantive, specific disclosure - named standard, actual detection limit, and a direct acknowledgment of the sealing-dot construction - not just a bare "lead-free" claim.

Products to avoid
Documented so you know what to skip — each still has a full breakdown and sources.
Rambler Jr Kids Bottle (12oz, Straw Cap)
A durable 18/8 steel kids bottle, but the Straw Cap is BPA-free plastic and the child drinks up through a plastic straw and cap - not plastic-free despite the premium steel reputation.
Rambler Tumbler with MagSlider Lid (20/30oz)
A rugged 18/8 steel tumbler, but the MagSlider lid is clear BPA-free Tritan plastic with a plastic magnetic slider - you drink over plastic every sip.
