YETI Rambler 20 oz Tumbler Stainless Steel — Solar Flare, Vacuum Insulated with MagSlider Lid

The YETI Rambler 20 oz Tumbler in Solar Flare is a stainless-steel, double-wall vacuum insulated cup with a magnetic MagSlider lid designed to keep drinks hot or cold and fit standard cup holders.

Engineered for day-to-day use and outdoor adventures alike, this 20 oz Rambler combines rugged stainless steel construction, YETI’s double-wall vacuum insulation, and a splash-resistant MagSlider lid. The tumble-resistant Duracoat finish in Solar Flare resists chipping and fading, while the No Sweat Design prevents condensation. Sized to fit most cup holders and rated dishwasher-safe, it’s built to be both functional and low-maintenance.

How long will the Rambler keep my drink hot or cold?

The double-wall vacuum insulation reduces heat transfer so hot beverages cool slower and cold drinks stay chilled longer than in a single-wall cup. Performance varies with environmental conditions and initial liquid temperature, but the Rambler’s construction minimizes temperature loss under normal use.

• Double-wall vacuum insulation for temperature retention
• Stainless steel interior resists flavor transfer
• MagSlider lid reduces exposure to air, slowing heat exchange

Is the MagSlider lid leakproof and easy to use?

The MagSlider lid uses a magnetic slider to open and close the drinking area, keeping splashes to a minimum and making one-handed access straightforward. It creates a protective barrier but is not fully leakproof—avoid tipping a full cup in a bag or on uneven terrain.

• Magnetic slider for smooth opening and closing
• Splash-resistant design for fewer spills during casual use
• Easy to remove and dishwasher safe for cleaning

How durable is the Rambler 20 oz and does the finish hold up?

Built from kitchen-grade stainless steel, the Rambler resists dents and punctures better than thin-walled tumblers. The Duracoat exterior is formulated to resist peeling, cracking, and fading so the Solar Flare color stays vibrant through repeated use.

• Durable stainless steel body for long-lasting strength
• Duracoat finish resists chips and fading
• No Sweat Design prevents condensation on the exterior

Will this tumbler fit in my car cup holder and is it easy to clean?

The Rambler 20 oz is sized to fit most standard cup holders with a 3 1/2 inch lip diameter and 6 7/8 inch height. It’s dishwasher-safe and BPA-free, making cleanup quick whether you rinse by hand or use the dishwasher.

• Compact 6 7/8 in height fits many cup holders
• Dishwasher-safe components save time on cleaning
• BPA-free materials for safer everyday use

Who is this for: The YETI Rambler 20 oz Tumbler in Solar Flare suits commuters, outdoor enthusiasts, and anyone who wants a reliable, low-maintenance cup that retains temperature and stands up to daily wear. It’s a good choice if you need a tumbler that fits standard cup holders, offers spill-reducing lid coverage, and keeps drinks at the desired temperature during a typical workday, hike, or road trip.
