Klean Kanteen
Built the whole company around getting plastic out of the water bottle, and it shows: the body, cup, and most caps are 18/8 stainless, with plastic pushed out to the parts that are hardest to replace — threaded closures and straw bits, where they've steadily moved from polypropylene toward silicone and steel. Where plastic remains it's a functional closure, not a food-contact surface you drink from, and they say so plainly.
How clear are their specs?
Product pages name the exact steel grade (18/8), call out recycled content, and specify closure materials (silicone vs. PP) per cap. Little guesswork needed — most of what we cite comes straight from their own listings.
Lead testing disclosure
Klean Kanteen's own FAQ states products undergo "regular product performance and material safety testing through third-party, accredited laboratories" and specifically claims to meet and exceed FDA, CPSIA, California Prop 65, and REACH - naming standards, not just a bare "lead-free" claim. It also explains the mechanism (silica/glass sealing plugs instead of lead solder in vacuum-insulated models) rather than just asserting the conclusion. No raw ppm/detection-limit numbers are published, and no single named lab report is cited, so it's solid but short of Made In/Kiddobloom-level specificity. Independent Lead Safe Mama XRF testing of Klean Kanteen's single-wall bottles has separately found them lead-free, consistent with the brand's claim.

Products we list
Classic with Steel Loop Cap
The plain Klean Kanteen Classic bottle paired with the all-steel Loop Cap - the drink touches only 18/8 stainless, sealed by a single replaceable silicone gasket.
Kid's Cup with Steel Straw Lid
Steel cup with a stainless steel straw and a silicone lid/flex-tip - the child drinks through steel, so the only non-steel water contact is silicone.
Kid's Cup with Straw Lid
Recycled-steel cup with a stainless steel straw and silicone lid/flex-tip - no plastic in the drink path, unlike the older PP sippy cap.
Reflect
Klean Kanteen's flagship plastic-free bottle - three materials only (steel, bamboo, a silicone gasket), so water only ever touches stainless steel.
TKPro Insulated Thermos
A fully plastic-free insulated thermos - all 18/8 steel and silicone, with a leakproof 360-degree pour-through cap and a steel serving cup. Discontinued by Klean Kanteen; see the TKWide Insulated + Wide Loop Cap for the current equivalent.
TKWide Insulated with Wide Loop Cap
The insulated TKWide bottle fitted with Klean Kanteen's Wide Loop Cap, whose one-piece stainless interior keeps the drink on steel - a leakproof, steel-and-silicone path and the current stand-in for the discontinued TKPro thermos.
Kid Classic with Sport Cap
Steel Kid Classic body, but the Sport Cap 3.0 kids drink through is polypropylene plus a silicone spout - so water does touch plastic at the cap.
TKWide Insulated Tumbler with Café Cap
All-steel insulated body, but the popular Café Cap sips through a polypropylene spout - a corrective for the common assumption that a Klean Kanteen coffee mug is plastic-free.
