YETI Rambler 16 oz Stackable Tumbler — Stainless Steel, Vacuum Insulated with MagSlider Lid and Ridgeline Base

The YETI Rambler 16 oz Stackable Tumbler is a tough, vacuum-insulated stainless steel cup with a MagSlider lid designed for everyday portability and temperature retention.

Built to endure daily commutes, outdoor days, and cramped kitchen cabinets, this 16-ounce Rambler balances low-profile portability with YETI's signature durability. Its stackable shape saves space at home or in a glovebox, while dishwasher-safe stainless construction keeps maintenance simple. The MagSlider lid offers an extra barrier against spills without creating a leakproof seal, and the Ridgeline base helps it sit securely in most cup holders.

How well does it keep drinks hot or cold?

The Rambler uses double-wall vacuum insulation to slow heat transfer so hot beverages stay warm and cold drinks stay chilled longer than single-wall cups. While duration depends on starting temperature and environment, the Rambler reduces temperature change significantly for everyday use.

• Double-wall vacuum insulation reduces heat and cold exchange
• Stainless steel construction prevents flavor transfer
• MagSlider lid minimizes exposure to air for better temperature retention

Is the MagSlider lid spillproof and easy to use?

The MagSlider lid provides a magnetic closure that helps keep your drink contained and slows temperature loss, but it is not fully leakproof. It glides open and closed for one-handed sipping and is simple to remove for cleaning or stacking the tumblers.

• Mag-snap action for convenient one-handed access
• Not designed to be leakproof—avoid tipping in bags
• Removable for dishwasher cleaning and compact storage

Will it fit in my cup holder and save space at home?

The Rambler’s Ridgeline base and 16 oz profile were designed to fit most vehicle cup holders and stack efficiently with other Ramblers when lids are removed. This makes it easy to transport and quick to store in crowded cabinets or backpacks.

• Ridgeline base improves cup holder stability during travel
• Stackable design saves cabinet and gear space
• Compact 16 oz volume balances capacity and portability

How do I care for the tumbler?

The Rambler is dishwasher safe, but occasional handwashing the lid helps maintain the MagSlider mechanism. Use mild detergents and avoid abrasive pads on the powder coat to preserve the finish.

• Dishwasher-safe stainless steel body for easy cleaning
• Remove lid components for thorough washing
• Avoid bleach or harsh cleaners to protect finish and seals

Who is this for? The YETI Rambler 16 oz Stackable Tumbler suits commuters, outdoor enthusiasts, and anyone who wants a rugged, easy-to-store cup that balances thermal performance with everyday convenience. It’s a smart pick if you need a dependable tumbler that fits cup holders, stows neatly, and stands up to frequent use without fuss.
