What Vacuum Insulated Tumbler (11 oz) is made of, ingredients and materials
This tumbler uses a double-wall stainless steel construction (interior and exterior) with a vacuum seal between them, which eliminates direct contact between beverages and plastic. The plastic lid is the only food-contact polymer component. Vacuum-insulated designs inherently avoid the leaching risks of metal-lined plastic bottles or ceramic-coated alternatives because the beverage never touches the stainless steel surface or any adhesive layer.
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.
BPA & bisphenols
The brand does not publicly disclose lid polymer type or BPA-free status. Risk is low because the lid contacts only the mouth and air space, not the beverage itself, but clarification of lid resin would strengthen safety profile.
Source, FDA ↗Lid seal degradation and bacterial growth
If the seal gasket is not food-grade silicone or if it cracks, trapped moisture can harbor bacteria. This is a maintenance issue, not a manufacturing defect, but replacement gaskets are often unavailable for secondary brands.
Vacuum seal loss over time
Vacuum-seal integrity can degrade after 2-5 years of normal use; a compromised seal does not create a safety hazard but reduces insulation and may allow condensation inside. This is wear-and-tear, not a chemical safety concern.
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, chromium)
Food-grade stainless steel (typically 304 or 316) is highly stable and does not leach under normal use. No recalls or complaints are documented for tumblers on this basis.
Off-gassing or odor transfer from plastic components
No specific odor or VOC complaints are recorded for tumblers. Plastic lids from reputable suppliers are typically stabilized and do not off-gas at room temperature.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand is known primarily for luggage and travel accessories; vacuum tumblers are a secondary product line. No public record exists of recalls, safety certifications, or specific material disclosures for this model. The brand's silence on PFAS is typical for mid-tier drinkware manufacturers and does not indicate hidden use; it reflects minimal transparency culture rather than a known problem.
How it compares in its category
Vacuum-insulated tumblers are among lower concern reusable drinkware options because stainless steel is not a material linked to PFAS leaching across normal temperature ranges. This design outperforms ceramic-coated steel (glaze-leaching risk), plastic-lined alternatives (polymer leaching risk), and uninsulated aluminum (direct leaching from acidic drinks). The brand's 11 oz size is standard and carries no known design defects compared to competitors like Hydro Flask or YETI.
If you buy it
Wash the lid thoroughly by hand or in the top rack of a dishwasher; inspect the seal annually for cracks or degradation and replace if compromised. Avoid prolonged contact with boiling water above 195F (stainless steel vacuum seals can weaken under extreme sustained heat). Do not use solvents or abrasive scrubbers on the interior, as micro-scratches in stainless steel are rare but could theoretically harbor bacteria. Replace the lid if cracks appear in the plastic or seal; the tumbler body itself typically lasts indefinitely.
