YETI Rambler 20 Oz Tumbler

Bigger than the 10oz Rambler but still built for a single, longer drink, the YETI Rambler 20oz Tumbler in Stag Red holds 591ml of coffee, iced tea or water in the same puncture-resistant stainless steel used across YETI's range. Double-wall vacuum insulation keeps drinks at temperature for hours, and at 0.4kg empty it's still light enough to carry around without feeling like a chore. The included MagSlider lid closes with a simple magnetic slide, adding a layer of splash protection for a desk, car or kitchen counter.

Key Features

• 591ml capacity: Enough for a full coffee, a large iced drink or a proper serving of water.
• Kitchen-grade stainless steel: Resistant to punctures and rust, and BPA-free throughout.
• Double-wall vacuum insulation: Maintains temperature for hours in either direction, hot or cold.
• MagSlider lid: Magnetically closes for splash resistance, with gaskets that come apart for cleaning.
• No handle, cupholder compatible: Sized to fit standard cupholders despite the larger capacity.
• Dishwasher safe: Lid on the top rack, gaskets and magnetic caps in the utensil basket.
• Five-year warranty: Backed by YETI against manufacturing defects.

At Urban Industry We Recommend These For

• A full working day at a desk, where 591ml means fewer refills.
• Long car journeys, still fitting most cupholders despite the larger size.
• Iced coffee and cold brew, where the bigger capacity suits a larger serving.
• Anyone upgrading from the 10oz tumbler who wants more capacity without moving to a handled mug.
• Keeping a cold drink cold through an afternoon outdoors without needing a full bottle.

Fit & Sizing Recommendations

• Our team's guidance on fit: 591ml sits well above the 10oz tumbler, so it suits a full drink rather than a quick top-up.
• At 8.8cm wide, check it against your cupholder if you're planning to use it mainly in the car, as it's noticeably wider than the 10oz version.
• The MagSlider lid is splash resistant rather than leakproof, so it's best kept upright rather than packed into a bag.
• Without a handle, it's designed to be picked up and held rather than carried by strap or clip.

Washing & Care Instructions

• Put the lid on the top rack of the dishwasher, with the magnetic cap and gasket in the utensil basket.
• Hand wash the steel body if you prefer, using warm water and mild soap.
• Rinse promptly after use, particularly with drinks like coffee or juice that can stain the inside.
• Don't use it for carbonated drinks, as sealed pressure can build up.
• Keep it out of prolonged direct sunlight or heat to protect the finish.
