YETI Rambler 30 oz Stainless Steel Tumbler with MagSlider Lid — Vacuum Insulated, No-Sweat Design

The YETI Rambler 30 oz stainless steel tumbler with MagSlider lid is a rugged, double-wall vacuum insulated cup designed to keep hot drinks hot or cold drinks cold while preventing condensation.

Built from 18/8 stainless steel and fitted with YETI’s magnetic MagSlider lid, this 30-ounce Rambler balances heavy-duty durability with everyday convenience. It’s BPA-free, dishwasher-safe, and sized to fit most standard car cup holders. Whether you’re commuting, working outdoors, or relaxing at home, this tumbler is engineered to protect your drink’s temperature and resist dents and dings.

How does the MagSlider lid improve everyday use?

The MagSlider lid uses a magnet to keep the opening secure without relying on a gasket seal, so sipping is simple and the lid stays where you need it. It helps reduce splashes and makes one-handed use easier when you’re on the move.

• Magnet-secured slider for a reliable closure
• Easy one-handed sipping and re-sealing
• Designed to reduce spills versus open-top tumblers
• Removable for cleaning and dishwasher-safe components

Will this Rambler actually keep temperature for hours?

The Rambler’s double-wall vacuum insulation minimizes heat transfer so cold stays cold and hot stays hot longer than single-wall cups. While exact duration depends on liquid and environment, the vacuum construction noticeably slows warming or cooling.

• 18/8 stainless steel body resists temperature change
• Double-wall vacuum insulation for extended temperature retention
• Ideal for coffee, iced drinks, or evening beverages
• Holds 30 ounces—enough for large servings without frequent refills

Is this tumbler tough enough for outdoor use?

Yes — the Rambler is built for active use with a robust stainless shell and impact-resistant finish. It’s engineered to withstand bumps and drops that happen during travel, camping, or hands-on days at work.

• 18/8 stainless steel resists rust and denting
• No Sweat Design prevents exterior condensation
• Dishwasher-safe for easy cleanup after outdoor trips
• Sized to fit most standard cup holders for travel convenience

What are the practical dimensions and maintenance tips?

The YETI Rambler 30 oz stands 7 5/8 inches tall with a 4-inch lip diameter, sized to slide into common cup holders while offering a large capacity. Cleaning is straightforward: the tumbler and many lid parts are dishwasher-safe, and periodic hand-washing of the lid components helps maintain the magnetic slider.

• Height: 7 5/8 inches; lip diameter: 4 inches
• 30-ounce capacity for fewer refills during the day
• BPA-free materials and dishwasher-safe construction
• Hand-wash lid pieces when possible to preserve the magnet and seal

Who this is for: The YETI Rambler 30 oz is a fit for commuters, outdoor enthusiasts, parents, and anyone who wants a high-capacity, durable tumbler that maintains drink temperature and resists condensation.
