We over-engineered these double-wall insulated tumblers with an 18/8 stainless steel body, which means your drink still keeps its temperature no matter how much of a beating this cup takes. These YETI® Ramblers® come standard with our YETI® MagSlider™ Lid, the only drink lid that uses the power of magnets to keep your water, beer, or favorite drink on lock. **Shipping available to U.S. addresses only. Not available blank.** 18/8 STAINLESS STEEL Resists dents and drops. DOUBLE-WALL VACUUM INSULATION keeps drinks cold to the last drop. DISHWASHER SAFE Because no one needs more work to do. NO SWEAT DESIGN prevents condensation, keeping hands dry. DURACOAT COLOR If your Rambler Drinkware comes in DuraCoat™ Color, rest assured it won't peel or crack. Cupholder compatible.
