OtterBox Elevation Tumbler
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes stainless steel, copper lined, powder-coated finish, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What OtterBox Elevation Tumbler is made of, ingredients and materials
The Elevation Tumbler uses 18/8 stainless steel as the primary material, with a copper thermal lining for insulation. A powder-coated finish (color layer) covers the exterior. Stainless steel is chemically stable and does not leach metals into beverages under normal use, and copper as an interior thermal layer does not contact liquids directly. Powder coating is a dry, baked-on finish that poses minimal leaching risk if intact.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Powder-coat degradation over time
The exterior powder finish can chip or wear with heavy use or drops, exposing bare stainless steel. While stainless steel is not a material linked to PFAS, aesthetic degradation may raise concerns about protective integrity. No specific coating composition is disclosed by the brand.
Stainless steel nickel content
18/8 stainless steel contains approximately 8% nickel, which is leached minimally into neutral beverages but can migrate into acidic or salty liquids over time. This is a general material property, not a defect, and risk is low for typical daily use. People with nickel sensitivity may wish to consult their physician.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lid material and gasket composition
The product context does not specify lid material (plastic, silicone, or hybrid). If plastic lids are present, they could contain BPA or phthalates; this requires verification from the manufacturer or product documentation, which is not provided here.
Copper thermal lining leaching
Copper linings in insulated drinkware are sealed from liquid contact by the stainless steel exterior layer. No cases of copper leaching from intact OtterBox tumblers have been reported. Risk would only emerge if the interior seal is compromised or damaged.
Lead
Powder coatings can theoretically contain heavy metals as pigments or stabilizers, but OtterBox is a reputable brand and no recalls or test reports indicate contamination. No public safety data contradicts the safety of this product's finish.

The brand's record and disclosure
OtterBox is known for rugged protective products and has not published transparency reports on material safety or PFAS use. The brand has not made public commitments to avoid PFAS in drinkware. No recalls or safety controversies related to the Elevation Tumbler are on record. OtterBox's silence on chemical disclosures is typical for non-food-safety-regulated drinkware makers but limits independent verification.
How it compares in its category
Stainless steel insulated tumblers have lower concern for PFAS because the material is inert and does not require protective coatings on the contact surface. Many competitors use plastic liners or BPA-containing lids; the Elevation's all-metal construction avoids this. Pricing and durability are competitive, though some premium brands (Hydro Flask, S'well) publish more detailed material certifications.
If you buy it
Hand wash or use top-rack dishwasher to preserve the powder coat; avoid prolonged contact with acidic beverages (citrus, vinegar) which can gradually corrode stainless steel at microscopic levels. Do not use for temperatures above 100°C (boiling water is acceptable for short durations). Replace the lid seal if it cracks or becomes loose. The tumbler itself should last years with normal care; monitor the seal and exterior coating for damage that might compromise insulation.
