• bamboo or stainless cap

Common claims

• Certified Climate Neutral
• BPA-free
• Lifetime guarantee

Concerns / watch-outs

• Some older insulated models used a plastic liner — verify on newer models
• Stainless-on-stainless threading can cross-thread if rushed

Notes

One of the most reputable stainless bottle brands. Certified B Corp and Climate Neutral. A top pick for safe daily hydration.

Cleaner alternatives

• stainless water bottle
• kinto water bottle

Materials

• Borosilicate glass
• BPA-free plastic snap lids

Common claims

• Oven, microwave, and freezer safe
• Non-porous glass
• BPA-free lids

Concerns / watch-outs

• Lids are typically polypropylene (PP) — avoid microwaving with lid on

Notes

Best practice for food storage. Glass body is completely inert. Just don't microwave with the plastic lid on to avoid leaching.
