Simple Modern Trek Pivot Kids Flip Straw Tumbler
Lower concern. Plastic tumbler with no known PFAS risk markers identified.
Simple Modern's Trek Pivot uses Tritan plastic, which is inherently PFAS-free. No waterproof coating, nonstick surface, or stain-resistant treatment typical of PFAS products. No brand disclosure on PFAS.

The full breakdown
What it's made of and why it matters
The Trek Pivot tumbler body is Tritan copolyester, a BPA-free polyester variant designed for durability and temperature resistance without the endocrine concerns of polycarbonate. Stainless steel components (lid mechanism, hinges) eliminate metal leaching risks from aluminum or coated zinc alloys. Tritan does not degrade significantly at typical beverage temperatures and has no documented history of microplastic shedding in the published literature, though no product is absolutely exempt from mechanical wear over years of use.
The brand's record and disclosure
Simple Modern does not publish detailed material safety data sheets or third-party certifications (e.g., FDA food-contact compliance statements) on their website, which is common for mid-market drinkware brands. No major safety recalls, contamination incidents, or litigation affecting this model appear in public records. The brand has not publicly committed to PFAS elimination or transparency, though the product itself shows no markers of deliberate PFAS incorporation.
How it compares in its category
Kids' tumblers in this price range typically use Tritan, polypropylene, or silicone; Tritan is a middle-ground choice offering better thermal stability than PP but less rigidity than borosilicate glass. Simple Modern's stainless steel hardware is more durable than plastic-only alternatives, reducing replacement frequency. Compared to silicone-body tumblers, this product is less flexible but more scratch-resistant and less prone to odor retention.
If you buy it
Hand wash or place on top rack of dishwasher; Tritan tolerates standard hot water but should not be filled with liquids above 60 degrees Celsius (140 Fahrenheit) repeatedly, as prolonged heat can soften seals. Inspect the straw, flip lid mechanism, and seal gasket annually for cracks or degradation; replace straws and gaskets if cracked, as these are wear items. Store dry and away from direct sunlight to slow UV degradation of the plastic body over 3 to 5 years of regular use.
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.”
Microplastic generation from plastic body wear
Tritan copolyester is mechanically durable, but any plastic tumbler subjected to repeated thermal cycling, impact, and abrasion may shed microscopic particles over years. No published studies document significant microplastic release from intact Tritan tumblers during normal use, but the hazard cannot be ruled out if the body degrades.
Gasket and seal leachables
Silicone gaskets in the flip lid and straw connection are not disclosed in detail by Simple Modern. While food-grade silicone is standard, some lower-cost silicone compounds may leach oligomers at high temperatures; this risk is low under typical beverage conditions but increases with hot liquids or dishwasher heat.
Straw choking hazard (design-specific risk)
Flip straw tumblers are marketed for toddlers and young children. The silicone or plastic straw can detach or separate from the lid assembly; this is a known design-class risk noted in parent forums and product reviews, though not formally recalled by the manufacturer.
Lid mechanism durability and hinge stress
The pivot hinge connecting the stainless steel lid to the plastic body is a stress concentration point. Repeated opening and closing, especially by children, can cause plastic crazing or hinge loosening over 1 to 2 years, potentially exposing internal metal components or allowing liquid to pool in crevices where bacteria may grow if not dried immediately.
Lead or cadmium in stainless steel fasteners
Food-contact stainless steel (typically 18/8 or 304 grade) does not leach lead or cadmium under normal use. Simple Modern has not disclosed fastener specifications, but no recalls or complaints of heavy metal contamination from this product line are documented.
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.
