Lunch Food Box vs OGIO 96000 Sprint Lunch Cooler: which is safer?

Where these two actually differ

• We flag Bamboo fiber lid degradation or contaminant absorption, Gasket or seal material composition and Bamboo fiber formaldehyde or chemical treatment residue on the Klean Kanteen and not on the Oggi.
• We flag Waterproof coating composition (likely PFAS-based, assessed separately), Phthalates or plasticizers in polyester blend, Formaldehyde in fabric finishing resins and Microplastics shedding from degraded insulation layer on the Oggi and not on the Klean Kanteen.
• The Klean Kanteen is stainless steel with bamboo fiber lid where the Oggi is polyester with waterproof coating, unclear polymer type, which is most of the difference in these two grades.
• The gap is 75 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
• We are less certain about the Oggi grade, at 45% confidence against 78%, because it discloses less.
