What Simple Modern 20oz Classic Tumbler is made of, ingredients and materials
This tumbler uses a stainless steel interior with vacuum insulation (typically air gap between stainless steel walls), which is not a material linked to PFAS concerns for beverage containers. Stainless steel is chemically inert and does not leach metals, BPA, or other compounds into liquids across normal use temperatures. The lid and straw are typically made from plastic (likely polypropylene or similar food-grade polymer), which carry lower risk than older plastics but warrant brief inspection for visible degradation.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Plastic lid and straw degradation
The polypropylene or similar plastic lid and straw may crack, cloud, or shed microplastics if dropped repeatedly or exposed to high heat; no recall data exists for this model, but plastic food-contact components degrade over time in all products of this type.
Bacterial or mold growth in lid seals and straw
Insulated tumbler lids and straws have tight crevices where moisture can accumulate; if not cleaned thoroughly and dried, mold or bacterial biofilms can develop, independent of the tumbler material itself.
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
Food-grade stainless steel (typically 18/8 or 304 alloy) is chemically stable and does not leach nickel, chromium, or other metals into beverages under normal use; no established risk for this product category.
Adhesive or coating toxicity in vacuum seal
Simple Modern does not disclose the adhesive or bonding agents used in the vacuum-seal construction; stainless steel tumblers typically use food-safe epoxies, but independent verification is unavailable for this specific model.
BPA & bisphenols
Modern food-grade polypropylene lids and straws are typically BPA-free and phthalate-free by design, though Simple Modern has not published material safety data sheets; no recalls or testing failures are on record for this product line.

The brand's record and disclosure
Simple Modern has not published detailed material sourcing or chemical safety disclosures on its website or in accessible certifications. The brand has no known recalls or safety controversies tied to this tumbler line. Without formal third-party certification (NSF, FDA food-contact verification), buyers cannot independently confirm that all components meet food-contact safety standards, though stainless steel tumblers have no hazard of this kind on record with regulatory bodies.
How it compares in its category
Stainless steel insulated tumblers show lower concern for PFAS migration compared to ceramic-coated or plastic-lined alternatives that can degrade or leach over time. Simple Modern's design is typical for this category; competitors like Hydro Flask, YETI, and Contigo use similar stainless steel construction. The vacuum insulation eliminates the need for problematic coatings or adhesives found in some budget alternatives.
If you buy it
Hand wash the lid and straw regularly to prevent mold or bacterial buildup in crevices, especially if used for warm beverages. Inspect the plastic lid and straw annually for cracks, cloudiness, or visible wear; replace them if damaged to avoid microplastic shedding. Avoid prolonged storage of acidic beverages (lemon water, vinegar-based drinks) as stainless steel can corrode over decades of exposure, though this is rare with food-grade alloys. Do not microwave the plastic components.
