Keith Titanium
Keith builds bottles out of a single material - pure titanium, with no inner coating or paint - which is about as inert and plastic-free as a body gets. The one concession is the lid: their threaded and bayonet caps seal against a food-grade silicone gasket, so the bottles are silicone-only rather than fully plastic-free. Keith markets the bottles as "plastic-free," which is accurate for the titanium body and the metal cap shell, but the sealing ring is silicone.
How clear are their specs?
States Grade 1 pure titanium with no lining or coating, and describes the cap as a titanium shell with a food-grade silicone sealing ring - materials are named plainly on the product pages.
Lead testing disclosure
States on its own site and product listings that samples passed EU Food Grade (German LFGB) testing and U.S. FDA testing, both conducted by SGS - a named accredited third-party lab plus specific standards, not just a "food safe" claim. No raw ppm/detection-limit figures are published, which keeps this short of the strongest disclosures in the category.
