How we assess products
We work from published information; we do not lab-test, and a verdict here is never a claim that we have.
Low concern means the published materials we assessed show no known microplastic ingredient and no material microplastic concern. It does not mean:
- Not proof that no microplastic or nanoplastic particles are present or released — analytical methods have lower size limits, and nanoplastics largely escape detection.
- Not elimination of background exposure, which indoor dust and diet may dominate anyway.
- Not proven health safety — current science cannot substantiate that for any product.
- Not a general environmental or sustainability endorsement.
About This Product
Based on available material data, the Hydro Flask Standard Mouth uses TempShield double-wall vacuum insulation with a stainless steel interior and no interior coatings or plastic linings on the bottle body. Note that the Amazon option linked here comes with a straw lid, whose plastic straw does sit in the drink in use — choose the flex cap version for steel-only contact.
