OtterBox Elevation 28 Sport Bottle
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 28 Sport Bottle is made of, ingredients and materials
The Elevation 28 uses 18/8 stainless steel (chromium-nickel alloy) as the primary material, which is chemically stable and does not leach metals under normal use. The copper lining is bonded to the interior and contributes to thermal performance without direct food contact risk in typical beverage conditions. The exterior powder-coated finish provides durability and corrosion resistance but requires inspection over time for chips that could expose underlying steel.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Powder-coat finish degradation
OtterBox does not disclose the specific composition of the powder coat. While powder coatings are generally low-toxicity, flaking or chipping could expose underlying steel and is a maintenance concern rather than an acute safety issue.
Silicone gasket degradation
Silicone seals and caps can degrade with age and thermal cycling, potentially releasing trace silicone particles or causing seal failure. Replacement gaskets are readily available and recommended after 2-3 years of regular use.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Copper lining leaching
Copper bonded to stainless steel does not typically leach into beverages under normal pH and temperature conditions. No documented cases of copper contamination from this product line.
Heavy metals
18/8 stainless steel is food-grade and does not leach chromium or nickel under typical beverage use (neutral to slightly acidic liquids at ambient to warm temperatures). No documented leaching concerns for this material class.

The brand's record and disclosure
OtterBox is known for rugged protective products but has not published specific material safety certifications or PFAS statements for this drinkware line. The brand does not appear in major public controversies regarding heavy metals or coatings in water bottles, though transparency about finish composition and testing is limited. No recalls specific to this model are documented in public records.
How it compares in its category
Stainless steel insulated bottles have lower concern for BPA and phthalate risks compared to plastic alternatives in the drinkware category. The powder coat finish is standard for this product type and has lower concern for certain risks than some older painted or enamel finishes, though less transparent than brands that disclose coating chemistry. Price and durability position it competitively with Hydro Flask and Yeti models, which also lack detailed PFAS disclosures.
If you buy it
Inspect the powder-coated finish regularly, especially the rim and cap threads, and replace the bottle if flaking develops. Hand wash or use the top rack of a dishwasher, though repeated high-temperature dishwashing may degrade the finish over time. Avoid prolonged exposure to extreme heat (boiling liquids) or abrasive scouring. Replace the silicone seal or gasket if it shows wear, as degradation can allow leakage and reduce insulation performance.
