Contigo AutoSeal West Loop (16oz)
America's #1 travel mug has a steel body, but the AutoSeal push-button lid and drink spout are all plastic with silicone seals - you drink hot coffee through an all-plastic valve.
The verdict: Minimal plastic contact
The West Loop body is vacuum-insulated stainless steel, but the AutoSeal lid - the entire reason to buy a Contigo - is plastic. You press a plastic button to open a spring-loaded plastic valve and sip through a plastic spout, sealed with silicone. Hot coffee flows over an all-plastic mechanism on every sip. Included as a corrective: it is one of the best-selling travel mugs in the US and reads as a "stainless steel mug," but the drink path is entirely plastic - and it is hot liquid, contact-heavy plastic at that.

| Part | Material | Food contact |
|---|---|---|
| mug body (double-wall insulated) vacuum-insulated stainless steel body; grade unspecified by Contigo | Stainless Steel grade unspecified | Yes primary |
| AutoSeal lid body and push-button valve spring-loaded push-button valve; BPA-free plastic (Tritan/PP-family) | Plastic other / unspecified | Yes primary |

The Contigo AutoSeal West Loop is a mass-market favorite - often billed as America's #1 travel mug - built around the AutoSeal lid that seals itself between sips so it won't spill in a bag. You press a button to release a spring-loaded valve and sip through the spout; it's a one-piece lid that pops apart for cleaning. There's no lidless-sip option - the AutoSeal mechanism is the only way to drink from it. Convenient and genuinely leakproof.
Pros
- Genuinely leakproof AutoSeal lid; insulated stainless steel body
- Lid disassembles and is labeled BPA-free
Cons
- Drinking is only possible through the AutoSeal mechanism - no lidless sip design
- The push-button valve is fiddlier to clean than a simple lid
Notes
- The steel body is real, but there is no way to drink that avoids the plastic valve
