Klean Kanteen 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.
The verdict: Silicone only
Klean Kanteen builds the TKPro entirely from 18/8 stainless steel and silicone - no plastic anywhere, including the cap. The 360-degree pour-through lid stays on while you pour and seals leakproof with silicone gaskets, and the twist-off cup is steel. This is the community's answer to "a leakproof coffee thermos with no plastic in the path," and it is distinct from Klean Kanteen's TKWide + Cafe Cap, whose spout is polypropylene. You pour into the cup rather than sip through a mouthpiece, so the drink only ever touches steel and silicone.
What it's made of
| Part | Material | Food contact |
|---|---|---|
| thermos body (double-wall vacuum insulated) 18/8 food-grade stainless | Stainless Steel 304 / 18-8 | Yes primary |
| pour-through cap (inner) stainless inner lid; brand states the cap is stainless steel and silicone with no plastic | Stainless Steel 304 / 18-8 | Yes primary |
| cap gaskets / seals non-toxic silicone seals in the pour-through cap | Silicone | Yes seal |
| serving cup twist-off stainless cup that doubles as the lid cover | Stainless Steel 304 / 18-8 | Yes primary |
The TKPro is Klean Kanteen's high-retention thermos: double-wall vacuum steel that holds heat up to ~38 hours, with a 360-degree pour-through cap that lets you pour from any angle without removing the lid, and a stainless cup that screws over the top. It is a pour-into-a-cup thermos rather than a sip-through travel mug - you pour into the steel cup instead of drinking through a mouthpiece.
Pros
- Fully plastic-free - only steel and silicone, including the cap
- Leakproof 360-degree pour-through lid; pour without opening
- Outstanding heat retention (up to ~38h hot)
- Steel serving cup included; whole cap disassembles for cleaning
Cons
- You pour into the cup rather than sip directly - not a one-handed sip-lid travel mug
- Heavier and bulkier than a slim tumbler
- Steel cup and lip get hot with very hot drinks
- Pricier than a basic travel mug
Notes
- Sizes: 16oz, 25oz, 32oz, 1L
- Still common on the secondhand/clearance market; the TKWide Insulated + Wide Loop Cap is the current steel-interior replacement
- Marketed as 100% plastic-free; free of BPA, phthalates, and lead
