YETI Rambler 20 oz Tumbler Upland Birdie Olive — Stainless Steel, Vacuum Insulated with MagSlider Lid

The YETI Rambler 20 oz Tumbler is a rugged stainless-steel travel cup with double-wall vacuum insulation and a magnetic MagSlider lid to help keep drinks at their desired temperature on the go.

This 20 oz Rambler combines durable stainless steel construction, YETI's No Sweat design, and a magnet-secured sliding lid to offer a dependable tumbler for everyday use. The Upland Birdie Olive Duracoat finish resists chipping and fading, while the size fits most standard cup holders. It’s a straightforward option for commuters, outdoor enthusiasts, and anyone who wants a long-lasting cup that keeps beverages hot or cold longer than a basic mug.

How well does it keep drinks hot or cold?

The double-wall vacuum insulation minimizes heat transfer so hot drinks stay warm and cold drinks remain chilled for hours. It’s engineered to slow temperature change without relying on bulky insulation materials, making it easy to carry.

• Double-wall vacuum insulation for extended temperature retention
• Stainless-steel shell resists dents and helps preserve thermal performance
• MagSlider lid reduces heat/cold escape compared with open cups

Is the MagSlider lid leakproof and easy to use?

The MagSlider lid uses a magnet to hold a sliding panel in place, offering a convenient way to cover the drinking opening when not sipping. It provides splash resistance and helps retain temperature but is not fully leakproof, so avoid tipping the tumbler when filled.

• Magnetic slider secures the drinking opening quickly
• Offers splash and spill deterrence but not complete leak protection
• Simple to operate one-handed—useful when driving or hiking

How durable and easy to maintain is the Rambler?

Constructed from kitchen-grade stainless steel with a tough Duracoat color finish, the Rambler is built for repeated use and rough handling. It’s BPA-free and dishwasher safe, so cleaning is low-effort and the exterior finish resists cracking or peeling.

• Duracoat finish resists chipping, peeling, and fading
• No Sweat design keeps hands dry and prevents condensation rings
• BPA-free materials and dishwasher-safe parts for easy cleaning

Will it fit in cup holders and everyday gear?

The 20 oz Rambler measures approximately 6 7/8 inches tall with a 3 1/2 inch lip diameter, designed to slot into most standard cup holders and vehicle consoles. Its profile balances capacity with portability so you get a substantial drink without an oversized footprint.

• 20 oz capacity for ample hydration or coffee servings
• Sized to fit standard car and stroller cup holders
• Compact enough for backpacks and most beverage sleeves

Who is this for: This YETI Rambler 20 oz Tumbler in Upland Birdie Olive suits anyone who needs a resilient, everyday travel cup—commuters, outdoor adventurers, parents, and desk workers alike. If you want a tumbler that resists wear, maintains drink temperature longer than single-wall cups, and offers a magnet-secured lid for easier sipping, this model is a practical choice. Note that while the MagSlider adds convenience and splash resistance, it is not intended to be fully leakproof.
