YETI Rambler 20 oz Tumbler Stainless Steel — Cape Taupe, Vacuum Insulated with MagSlider Lid

The YETI Rambler 20 oz Tumbler is a rugged stainless-steel insulated cup with a magnetic MagSlider lid that keeps drinks hot or cold and fits most cup holders.

Whether you commute, camp, or sip at your desk, the Rambler 20 oz is built to hold temperature, resist bumps, and stay comfortable to hold. It combines double-wall vacuum insulation, durable stainless steel construction, and YETI’s No Sweat Design so condensation won’t drip onto surfaces. The Duracoat finish in Cape Taupe gives the tumbler a long-lasting color that won’t easily chip or fade, while the slim 20 oz profile slips into standard cup holders for everyday convenience.

How does this tumbler keep drinks hot or cold?

The Rambler uses double-wall vacuum insulation and stainless steel to slow heat transfer, preserving beverage temperature for hours. The tight rim and MagSlider lid reduce heat exchange at the top of the cup.

• Double-wall vacuum seals air out to minimize thermal transfer
• 18/8 stainless steel construction resists corrosion and retains temperature
• MagSlider lid adds a magnetic barrier to slow heat loss and splashes
• No Sweat Design prevents exterior condensation, keeping hands and surfaces dry

Is the MagSlider lid leakproof and dishwasher safe?

The MagSlider lid uses a magnet to make sipping simple and reduce spills, but it is not fully leakproof—avoid tipping the cup to prevent spills. Both the tumbler and the MagSlider lid are dishwasher safe for easy cleaning.

• Magnetic slider secures the opening during transport but won’t stop all leaks
• Top-rack dishwasher safe; rinsing before loading is recommended
• Lid provides a barrier to splashes and slows temperature loss
• Easy to remove and reattach for refilling or washing

Will the 20 oz Rambler fit in my car cup holder and how big is it?

The Rambler 20 oz is designed to fit most standard cup holders and daily-use spaces. It measures approximately 6 7/8 inches tall with a 3 1/2 inch lip diameter, offering a slim profile that balances capacity and portability.

• Height: about 6 7/8 inches for easy storage in bags and vehicles
• Lip diameter: about 3 1/2 inches to fit most holders and be comfortable to drink from
• Sized to fit standard-sized cup holders in cars and office furniture
• Compact enough to carry yet large enough for a generous serving

How durable is the Cape Taupe finish and overall construction?

The Rambler is built from tough stainless steel with a Duracoat colored finish formulated to resist chipping, peeling, and fading over time. YETI designed the tumbler for active use—whether outdoors or everyday life—so it stands up to bumps and repeated washes.

• Duracoat finish on colored tumblers resists cracking and fading
• 18/8 stainless steel resists dents, rust, and flavor transfer
• BPA-free materials ensure safe contact with beverages
• Dishwasher safe for convenience without compromising the finish
