YETI Rambler 20 oz Tumbler — Stainless Steel, Navy with MagSlider Lid, Vacuum Insulated & No-Sweat

The YETI Rambler 20 oz Tumbler is a rugged, vacuum-insulated stainless steel cup with a magnetic MagSlider lid that keeps drinks at the temperature you want while resisting dents and sweat.

Built for life on the move, this 20 oz Rambler pairs double-wall vacuum insulation with an 18/8 stainless steel construction and YETI’s magnetic MagSlider lid to minimize spills and lock in temperature. The tumbler’s Dracut color finish is formulated to withstand extended use without peeling or cracking, and the no-sweat exterior keeps hands dry. Sized to fit most car cup holders and dishwasher safe, it’s designed to be a durable everyday companion for commuting, outdoor adventures, or working at your desk.

How well does the Rambler keep drinks hot or cold?

The Rambler uses double-wall vacuum insulation and stainless steel to limit heat transfer, so hot drinks stay warmer and cold drinks stay colder for longer than in single-wall cups. It’s engineered to maintain the beverage temperature through normal daily use, even when exposed to outdoor conditions.

• 18/8 stainless steel inner and outer walls resist heat conduction
• Double-wall vacuum insulation slows temperature loss and gain
• MagSlider lid reduces heat escape and limits spills
• Durable finish helps maintain insulating performance over time

Is the MagSlider lid leakproof and easy to use?

The MagSlider lid uses a magnet to hold the sliding closure in place for spill resistance and convenient sipping. It’s not a fully sealed, pressurized lid, but it reduces splashes and is simple to open and close with one hand.

• Magnetic slider aligns and stays put for stable sipping
• Wide opening for easy drinking and ice access
• Designed to be removed for thorough cleaning and dishwasher safe parts
• Low-profile shape fits under most coffee machines

How durable is the stainless steel and Dracut finish?

The Rambler is built from 18/8 stainless steel that resists dents, rust, and corrosion better than thinner metals. The Dracut color coating is formulated to withstand scuffs and long-term field use without fading or peeling, while adding grip to the exterior.

• 18/8 stainless steel body resists impact and wear
• Dracut finish offers scratch resistance and added traction
• No-sweat design prevents exterior condensation and keeps hands dry
• Dishwasher-safe construction for easy maintenance

Will this cup fit in my car and handle everyday use?

The 20 oz Rambler stands about 6 7/8 inches tall with a 3 1/2 inch lip diameter, dimensions chosen to fit most standard cup holders and coffee machines. It’s sized and shaped for everyday routines, from commuting to hiking, and made to tolerate the knocks and drops of active use.

• 6 7/8 inches tall and 3 1/2 inch lip diameter fits most cup holders
• Compact enough for backpacks yet tall enough for generous pours
• Dishwasher-safe and BPA-free materials for everyday convenience
• No-sweat exterior prevents rings on tables and improves grip
