YETI Rambler 20 oz Tumbler Stainless Steel — Desert Bloom, Vacuum Insulated with MagSlider Lid

The YETI Rambler 20 oz Tumbler in Desert Bloom is a double-wall, vacuum-insulated stainless steel cup with a magnetic MagSlider lid built to keep drinks at the temperature you want while fitting standard cup holders.

The Rambler 20 oz blends rugged construction with a colorful Duracoat finish so you can carry coffee, iced tea, or water confidently. Designed for everyday use, this tumbler resists dents and fading, features a sweat-free exterior, and includes YETI’s MagSlider lid to reduce splashes while drinking. It’s dishwasher safe, BPA-free, and sized to slide into most vehicle cup holders for convenience on the move.

How long will beverages stay hot or cold in the Rambler?

Thanks to double-wall vacuum insulation and stainless steel construction, the Rambler slows temperature transfer so hot drinks stay warm longer and cold beverages stay chilled. Actual duration varies with starting temperature and ambient conditions, but the design minimizes heat exchange.

• Double-wall vacuum keeps core temperature stable
• Stainless steel walls resist carrying heat through the cup
• MagSlider lid reduces heat loss from the drinking opening
• No Sweat Design prevents exterior condensation on cold drinks

Is the MagSlider lid leakproof and easy to use?

The MagSlider lid uses a magnet to secure the sliding closure, helping contain splashes and keeping the drinking area covered. It offers better containment than open tumblers, but it is not fully leakproof—tipping or pressure can still allow liquid to escape.

• Magnetic slider helps keep the opening closed between sips
• Simple single-hand operation for on-the-go use
• Not guaranteed spill- or leak-proof if inverted
• Removable for easy cleaning and dishwasher safe components

Will the Rambler fit in my car or office cup holder?

The 20 oz Rambler measures about 6 7/8 inches tall with a 3 1/2 inch lip diameter, deliberately sized to fit most standard cup holders and many beverage racks. Its tapered shape and common dimensions make it a practical choice for commuting or desktop use.

• Height: approximately 6 7/8 inches for common fitment
• Lip diameter: roughly 3 1/2 inches to match standard holders
• Slim base and smooth sides slide into car cup holders easily
• Durable finish prevents scuffs and holds up in bags or consoles

How is the Desert Bloom finish maintained and how durable is it?

The Desert Bloom color is applied with YETI’s Duracoat coating, designed to resist chipping, peeling, and fading under normal use. The tumbler is dishwasher safe, though hand washing can extend the life of the finish if you prefer to be extra careful.

• Duracoat provides long-lasting color retention
• Stainless steel core resists dents and deformation
• BPA-free materials for safe drinking contact
• No Sweat Design keeps exterior dry during cold use

Who is this for? The YETI Rambler 20 oz in Desert Bloom suits commuters, outdoor enthusiasts, and anyone who wants a durable, insulated cup that fits common cup holders and reduces spills during travel. It's a good match for people who value a toughness-first build, easy cleaning, and a colorful finish that resists wear. If you need completely leakproof transport for liquid stored under pressure or inverted, consider a sealed bottle; otherwise, the Rambler offers excellent everyday temperature retention and convenience.
