PFAS score
Contigo · Insulated Drink Tumblers & Travel Mugs
Contigo Kids Leighton Spill-Proof Stainless Steel Tumbler with Straw
Lower concern for PFAS. Stainless steel inherently safer than coated cookware.
Stainless steel tumblers are not coated with Teflon-family coating and present lower PFAS risk than nonstick cookware. Contigo does not disclose PFAS practices; inspect plastic lid components for water repellency treatments.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
