Is the YETI Rambler 20 oz Tumbler leakproof?

No. The MagSlider lid resists splashes but is not sealed, so it can leak if tipped or carried in a bag. It is best for desk and cup holder use.

How long does it keep drinks cold?

YETI rates it for hours of ice retention, and owners report ice lasting most of a day. Hot drinks stay warm through a typical commute.

Is it dishwasher safe?

Yes. The tumbler and the MagSlider lid are both dishwasher safe, though hand washing the lid slider keeps it sliding smoothly longer.

Does it fit in a car cup holder?

Yes. The 20 oz Rambler's tapered base fits most standard car cup holders, which is a common reason buyers pick this size.

How does it compare with the Stanley Quencher?

The Rambler is smaller, simpler and has no handle or straw, while the Quencher holds more and includes a straw. The YETI feels sturdier; the Stanley suits all-day hydration.

The tumbler and the MagSlider lid. No straw or extra lid is included.

About the YETI Rambler 20 oz Tumbler

The YETI Rambler 20 oz Tumbler is a stainless steel insulated cup with a sliding MagSlider lid, built for hot coffee and cold drinks on the go. Its double-wall vacuum insulation keeps ice for hours and holds heat through a long commute, and the 18/8 stainless body resists dents and rust. It is heavier and pricier than basic tumblers, and the lid is not fully leakproof, so it suits desk and car use more than a bag. Owners rate it highly for build quality and temperature retention; rivals like Stanley and Simple Modern undercut it but rarely match the fit and finish.
