Klean Kanteen 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.
The verdict: Silicone only
The TKWide Insulated body is 18/8 stainless steel, and Klean Kanteen's Wide Loop Cap has a one-piece vacuum-insulated stainless interior, so the surface your drink meets is all steel - the brand states the beverage never touches plastic. The cap seals with a food-grade silicone double gasket, and its outer housing is polypropylene that sits outside the drink path, so the water path is steel plus silicone: silicone-only. This is NOT how the bottle ships - the insulated TKWide comes with a plastic cap, and you buy the steel-interior Wide Loop Cap separately. It is the closest current equivalent to the discontinued TKPro thermos, though you drink by unscrewing the wide mouth rather than pouring into a steel cup.
The insulated TKWide ships with a polypropylene cap; this steel-interior Wide Loop Cap (a separate SKU) is what puts the drink path in steel plus silicone. Buy it separately.

Klean Kanteen's insulated TKWide bottle, set up the plastic-free way with the Insulated Wide Loop Cap. It's a vacuum-insulated leakproof bottle with a wide mouth and a steel swivel carry loop on the cap; the cap disassembles for cleaning. You drink by unscrewing the wide mouth - there's no sip spout or straw. With the TKPro thermos now discontinued, this body-plus-cap combination is the current in-production Klean Kanteen for a leakproof, insulated, steel-and-silicone drink path.
