Rambler 20 oz Stainless Steel Vacuum Insulated Tumbler w/MagSlider Lid

started with a simple frustration: coolers and drinkware that couldn't keep up with a full day outdoors. Two brothers set out to build gear that matched the demands of its users. That same uncompromising standard is built into every Rambler stainless steel tumbler, including this 20 oz insulated tumbler designed for daily use from the truck cab to the trailhead.

The engineering starts with double-wall vacuum insulation, a sealed airless chamber between 2 walls of 18/8 stainless steel that locks in temperature so your first sip and your last taste the same. The stainless steel is food-grade and BPA-free, so it won't absorb or transfer flavors between your morning coffee and your afternoon iced tea. The MagSlider Lid uses magnets to keep the slider locked over the opening, helping contain your drink on the move. Note: the MagSlider Lid is splash-resistant, not leakproof, and will not prevent spills if tipped. Both tumbler and lid go straight in the dishwasher.

Picture your morning coffee on the commute, iced water at the gym, hot cocoa at the campsite, or a cold beer on the tailgate. At 6 7/8 in tall with a 3 1/2 in lip diameter, the Rambler fits standard cup holders; check your single-serve brewer clearance before brewing directly into it. No Sweat Design keeps the exterior dry, so no condensation rings on your desk or dashboard.

The Duracoat color finish resists cracking, peeling, and fading through years of hard use. The vacuum-sealed chamber creates an insulating barrier that maintains beverage temperature significantly longer than single-wall drinkware. The Rambler line carries a 5-year warranty, a reflection of how stands behind the build.

Whether it's a hot coffee travel mug for the daily commute or a gift for someone who demands gear that performs, the Rambler 20 oz is built to last.
