What Ozark Trail 22 oz Vacuum Insulated is made of, ingredients and materials
This tumbler uses food-grade stainless steel (typically 18/8 or 18/10 alloy) for both interior and exterior surfaces with no polymer coating, enamel, or glaze applied. Bare stainless steel is chemically stable at ordinary temperatures and contact with beverages and does not leach nickel, chromium, or other metals into cold or warm liquids under normal use. The vacuum insulation layer is typically silica aerogel or air-filled, not foam that off-gases. No ceramic coating, non-stick treatment, or resin lining has been disclosed for this model.
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.
Lid and gasket degradation
Rubber gaskets and plastic lids are common failure points in low-cost tumblers. Degradation can compromise insulation and allow mold growth in the seal. Replacement parts are not widely documented as available for this model.
Seal integrity and bacterial growth
If the gasket or seal is cracked, moisture can accumulate in the insulation cavity or lid assembly. This creates potential for mold or bacterial growth if not dried thoroughly after washing. Regular inspection is necessary to prevent this.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Nickel leaching from stainless steel
Stainless steel 18/8 alloy leaches negligible nickel into cold and warm beverages under normal conditions. No published reports of measurable nickel migration from Ozark Trail or comparable bare stainless steel tumblers in beverage use.
Coating or adhesive off-gassing (if present but undisclosed)
Ozark Trail does not disclose whether any epoxy, polyester, or adhesive coatings are applied to interior seams or the vacuum layer. If present but unmentioned, these could emit VOCs. No third-party teardown or testing of this specific model is publicly available to confirm absence.
The full breakdown
The brand's record and disclosure
Ozark Trail is a Walmart house brand with limited published safety certifications or third-party testing reports available to consumers. The brand does not publicly disclose material sourcing, manufacturing standards, or quality control protocols. No recalls specific to this tumbler model have been reported in FDA or CPSC databases. The parent company (Walmart) has faced scrutiny on supply-chain transparency but not on this specific product category.
How it compares in its category
Stainless steel tumblers without coatings are not a material linked to PFAS, with material choice comparable to premium brands like Yeti or Hydro Flask. Unlike plastic-lined or epoxy-coated alternatives, this design eliminates polymer leaching and coating degradation risks. The Ozark Trail price point is significantly lower than competitors, though durability and insulation performance claims are not independently verified.
If you buy it
Wash by hand or dishwasher; stainless steel tolerates both without degradation. Use with cold, room-temperature, and warm beverages (up to ~65°C / 150°F); do not use for extended boiling-hot liquid storage as seal integrity is not rated for sustained high heat. Inspect the rubber gasket and lid seal annually; replace if cracked or degraded to prevent insulation loss. No special maintenance is required; stainless steel does not corrode from typical beverage contact.
