Klean Kanteen 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.
The verdict: Minimal plastic contact
The tumbler body is 18/8 stainless steel with a smooth steel drinking lip, so on its own the vessel is plastic-free. The catch is the cap most people buy it with: the leakproof Café Cap is built from stainless steel, polypropylene (#5), and food-grade silicone, and the sip spout your lips meet - and the coffee flows through - is the polypropylene. So with the Café Cap on, hot coffee runs over plastic every sip. It is included here as a corrective: a "Klean Kanteen coffee mug" is widely assumed plastic-free, but the standard coffee cap puts polypropylene squarely in the sip path. Drinking from the bare steel tumbler (or with the splash-only Tumbler Lid) keeps the drink on steel.

Klean Kanteen's wide-mouth insulated tumbler paired with the Café Cap, the leakproof lid that turns it into a to-go coffee mug. The steel body and its rounded steel lip are what people want it for; the Café Cap adds a leakproof sip spout on top. Klean Kanteen sells other lids for these bodies, including a splash-only Tumbler Lid you sip over the steel rim with.
Pros
- 18/8 steel body with a steel drinking lip; excellent build quality
- B Corp brand with strong plastic-free bona fides elsewhere in the line
- Café Cap is leakproof and fully disassembles for cleaning
Cons
- A truly steel sip path needs the bare tumbler or a different cap
- Marketed in a way that implies "plastic-free" when the coffee cap is not
Notes
- The splash-only Tumbler Lid is an open-drink lid: you sip over the steel rim, though that lid itself is plastic and not leakproof
