What Simple Modern Classic Tumbler with Straw is made of, ingredients and materials
The tumbler body is stainless steel, which is chemically inert and does not leach metals or chemicals into beverages under normal use. The lid and straw are plastic components, likely polypropylene (PP) or similar, which carry minimal inherent toxicity if BPA and phthalates are not added. Stainless steel tumblers show lower concern as reusable drinkware because the metal itself has no known leaching pathway into cold or moderately heated liquids.
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.
Microplastics
If the lid/straw are exposed to temperatures above their rated limits (typically 70-80°C for most food-contact plastics), visible degradation and potential microplastic shedding can occur. This risk applies mainly to very hot beverages and prolonged heat exposure, not typical daily cold or warm drink use.
Source, EPA ↗Lid/straw material composition uncertainty
Simple Modern does not publicly specify whether lids and straws are recycled, virgin, or contain additives beyond standard PP/silicone. Without material safety data, minor risk of unlisted additives or degraded recycled content remains. Direct inquiry with brand customer service is recommended if concerned.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
No recalls or testing reports available for Simple Modern tumblers specifically. If lid/straw are polypropylene (PP #5), BPA is not typically used; if they are polycarbonate or other plastics, confirmation from the brand is needed. Absence of disclosure does not confirm safety, but stainless steel body itself poses no BPA risk.
Source, FDA ↗Phthalates
Phthalates are not typically added to rigid food-contact plastics used in lids and straws, but soft plastic seals or gaskets could theoretically contain them if not specified. No recalls on record for this product. Brand does not provide material data sheets.
Source, ATSDR ↗Stainless steel leaching (unlikely due to material grade)
High-grade stainless steel (typically 18/8 or 304 grade used in drinkware) does not leach nickel, chromium, or other metals into non-acidic beverages at room or warm temperatures. No established hazard for this product category.
The full breakdown
The brand's record and disclosure
Simple Modern does not publicly disclose detailed material composition or provide third-party safety certifications on their website. The brand has no established history of recalls related to this product line or chemical contamination. Their silence on PFAS use in lid coatings or water-repellent treatments is common across the consumer drinkware industry and does not indicate a known problem, but transparency is limited.
How it compares in its category
Stainless steel tumblers with plastic lids are a mainstream, mid-tier safety choice compared to ceramic-lined or glass alternatives. They outperform single-use plastics and lower-cost tumbler brands that may use recycled or post-consumer plastic without material specifications. Simple Modern's construction appears comparable to competitors like Hydro Flask and YETI in material class, though those brands provide more detailed material disclosures.
If you buy it
Avoid exposing the plastic lid and straw to prolonged heat or boiling water, as heating can increase any potential leaching from plastic components. Replace the straw and lid every 12-18 months if they show visible wear, discoloration, or odor, as these indicate degradation. Hand-wash rather than dishwasher to extend plastic component life. Do not use for hot beverages above 65-70°C (150-160°F) if you want to minimize any plastic leaching risk, though short-term use with hot drinks poses minimal practical hazard.
