What OtterBox Elevation Wine Tumbler is made of, ingredients and materials
The OtterBox Elevation Wine Tumbler is constructed from food-grade stainless steel (typically 18/8 or similar austenitic alloy) with a vacuum-sealed double-wall design for insulation. Stainless steel does not leach metals under normal beverage use because the chromium oxide passive layer prevents iron and nickel migration into liquids at room and warm temperatures. The product contains no ceramic glaze, enamel coating, or Teflon-type coating (Teflon) nonstick surface, eliminating the primary hazard vectors for cookware in this category.
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.
Gasket and seal leachables
OtterBox does not publicly disclose the material composition of the lid gasket or seal. Most vacuum tumblers use silicone or rubber; if the seal contains phthalates or other plasticizers, prolonged contact with hot liquids could theoretically increase migration, though consumer reports of taste or odor contamination from OtterBox drinkware are absent.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Stainless steel leaching (nickel, iron, chromium)
Food-grade stainless steel does not leach metals into beverages at room or warm temperatures due to the passive oxide layer. No reports of leaching from OtterBox tumblers or similar vacuum-insulated stainless steel drinkware exist in public safety literature.
Coating degradation and flaking
This product has no applied enamel, ceramic, or polymer coating. The exterior powder coat or paint (if present) is not food-contact and poses no ingestion hazard. No degradation concerns are documented.
Heavy metals
Lid hardware (typically stainless or aluminum screws and hinges) is not food-contact and poses minimal risk. No recalls or contamination reports for OtterBox drinkware exist.

The brand's record and disclosure
OtterBox is primarily known for rugged phone cases and outdoor gear; the brand has not published detailed material safety disclosures or third-party certifications (NSF, FDA) for this tumbler line. No public recalls, contamination reports, or manufacturing controversies involving OtterBox drinkware are on record. The company's silence on PFAS is consistent with many consumer-goods manufacturers that have not yet adopted industry-wide transparency standards, but does not indicate use or non-use of PFAS.
How it compares in its category
Vacuum-insulated stainless steel tumblers are among the lowest-risk cookware and drinkware options because the base material is inert and uncoated. This product sits at parity with mainstream competitors like YETI, Hydro Flask, and Contigo in material safety terms. The primary differentiation is durability and drop-resistance (OtterBox's brand strength), not chemical safety, which favors this choice for active use.
If you buy it
Hand-wash or use standard dishwasher cycles; stainless steel tolerates both methods. Avoid prolonged exposure to acidic beverages (wine, citrus juice) beyond 24 hours if concerns about microabrasion exist, though this is cosmetic rather than a leaching risk. Inspect the seal annually for degradation; a failing vacuum chamber will not affect liquid safety but will compromise insulation. Replace the tumbler only if the stainless steel develops visible rust or pitting, which is rare with quality 18/8 steel.
