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.

Credible evidence identifies a particle source or release pathway. This describes concern within our scope, not a proven health effect.

About This Product

The Nalgene Sustain uses Tritan Renew, made with 50% certified recycled content. Tritan is BPA-free and more chemically stable than polycarbonate, but it remains a plastic polymer and it forms the entire liquid-contact surface of the bottle. Long-term shedding data for Tritan under repeated use, hot washing and abrasion is limited, so the amount released is unclear. For a drinking surface with no plastic in contact with the water, consider stainless steel or glass.

Materials

  • Tritan Renew copolyester
  • polypropylene lid
