Simple Modern Voyager Tumbler
Lower concern tumbler; no known PFAS in core materials.
Simple Modern Voyager is a stainless steel tumbler with plastic components. No public disclosure of PFAS or water-resistant coatings; core materials pose minimal inherent risk.

The full breakdown
What it's made of and why it matters
The Voyager Tumbler's core is food-grade stainless steel, which does not leach metals under normal use and resists corrosion. The plastic lid and base (typically polypropylene or similar commodity plastics) are secondary contact surfaces that do not typically present BPA or phthalate risks in this application, as stainless steel tumblers are not heavily regulated for such additives. The double-wall construction creates an air gap that further isolates plastic from liquids.
The brand's record and disclosure
Simple Modern does not publicly release detailed material safety certifications or PFAS statements, which is typical for mid-market drinkware brands. No recalls or safety incidents have been established for the Voyager line. The brand maintains a basic product-safety stance but does not exceed industry standard transparency on chemical content or manufacturing practices.
How it compares in its category
Stainless steel tumblers are among the safest reusable drinkware options and avoid common hazards found in ceramics (lead glaze), coated aluminum (Teflon-type coating, aluminum leaching), or heavily plastic-dependent bottles. The Voyager is competitively positioned; it offers similar safety profiles to brands like Hydro Flask or YETI, though those brands tend to publish more detailed material specifications. Price and insulation performance are the primary differentiators, not safety.
If you buy it
Wash the lid by hand if possible to extend its lifespan; dishwashers may degrade plastic seals over time. Avoid prolonged exposure to extremely hot liquids (above 180F) in the plastic base, though normal hot beverages are safe. Replace the lid if seals crack or degrade visibly, as this can affect insulation and allow bacterial growth in the wall cavity. The stainless steel body itself requires minimal maintenance and will last years with normal care.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Plastic lid/base degradation and bacterial growth
Repeated heating in dishwashers or contact with very hot liquids can weaken polymer seals and threads. Cracks in the lid allow moisture into the insulation cavity, where bacteria and mold may grow if not dried promptly.
BPA/phthalates in plastic components
No recalls or published findings of BPA or phthalates in Simple Modern Voyager lids or bases. Polypropylene and similar polymers used in this tier of tumbler are not typically formulated with these additives, though full material disclosure is not available.
Stainless steel nickel leaching
Food-grade stainless steel (typically 18/8 or 304 grade) used in this tumbler is passivated to prevent surface corrosion and nickel release. No established hazard for normal beverage storage; concerns arise only with prolonged contact with acidic or salty liquids at high temperatures, which is not typical use.
Off-gassing or odor from new plastic
New plastic lids may release mild odor or volatile compounds typical of commodity polymers. This dissipates within days of normal use and ventilation; it is a minor and self-limiting issue.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
