@purascans: YETI Rambler drinkware contains lead. That’s not an accusation — it’s in Yeti’s own manufacturing documentation. A lead-based sealing bead is used to create the vacuum insulation that makes the cup work. Yeti states the bead is fully encapsulated in stainless steel and inaccessible, and third-party leachable testing detects no lead in the drinkware. Independent XRF testing found the tumbler lead-free in all accessible components. The lead sits under the bottom cap. Yeti’s lifetime warranty covers that cap detaching. Most major insulated drinkware brands use the same method. Scanned with the Pura App
