YETI Rambler 10 oz Stackable Mug — Black, Vacuum Insulated with MagSlider Lid

The YETI Rambler 10 oz Stackable Mug is a compact, double-wall vacuum insulated stainless steel cup with a magnetic MagSlider lid designed to keep drinks at the desired temperature while resisting wear.

Small enough for tight spaces but engineered for performance, this 10 oz Rambler pairs YETI’s durable stainless-steel construction and No Sweat exterior with a MagSlider lid that uses magnets to help control splashes. The slim, stackable profile and tough Duracoat finish make it an easy choice for daily commutes, boat decks, and campsite mugs where durability and insulation matter.

How well does the Rambler 10 oz keep drinks hot or cold?

The double-wall vacuum insulation limits heat transfer so beverages maintain their temperature longer than single-wall cups. It won’t perform like a full-size thermos for multiple hours, but it dramatically slows cooling or warming for typical short-to-medium outings.

• Double-wall vacuum insulated stainless steel retards heat and cold transfer
• Small 10 oz capacity reduces exposed surface area for quicker retention
• MagSlider lid reduces heat loss at the drinking opening compared to open cups

Is the MagSlider lid leakproof and how does it work?

The MagSlider lid uses a magnetic slider to secure the drinking opening and minimize splashes while sipping. It provides an extra barrier against heat and cold loss but is not fully leakproof and will not prevent spills if tipped or inverted.

• Magnetic slider stays in place for easy one-handed use
• Helps contain splashes and reduces airflow loss through the opening
• Not designed to be sealed for leak-free transport—upright use recommended

What durability and care features should I expect?

The Rambler is built to take knocks: stainless-steel walls, a No Sweat exterior, and a Duracoat color that resists chipping or fading. It’s BPA-free and dishwasher-safe, which makes cleanup straightforward after daily use.

• 18/8 stainless steel construction resists dents and rust
• No Sweat design prevents exterior condensation for a dry grip
• Duracoat color finish resists cracking, peeling, and fading
• BPA-free components and safe for top-rack dishwasher cleaning

Will the mug fit cup holders and how big is it?

The compact dimensions make this mug easy to tuck into most cup holders and small storage spaces. With a 3.5-inch lip diameter and a 4-inch height, the handle brings the total width to nearly 5 inches, and the stackable shape saves space when storing multiple Ramblers.

• Stands 4 inches tall for low-profile storage
• 3.5-inch drinking opening fits many coffee machines and pour spouts
• Handle extends to almost 5 inches total width—comfortable grip
• Stackable design nests neatly with other Ramblers to save space

Who is this for: The YETI Rambler 10 oz Stackable Mug suits anyone who wants a tough, compact insulated cup for everyday routines—commuters, boaters, minimalists, and travelers who need reliable temperature control and a durable finish in a small package. Choose this mug if you value a spill-mitigating magnetic lid, rugged stainless-steel build, and a low-profile, stackable design for easy storage.
