This Might Be The Ultimate Camp Mug. It Has A Double-Wall Vacuum Insulation And It’s The Perfect Size To Enjoy Coffee, Chili, Or Ice Cream Longer. The Yeti® Magslider™ Lid Seals Your Mug To Prevent Splashes, And When Removed, The Bottom Grooves Allow Mugs To Nest Perfectly So You Can Stack Them And Save Space When Storing. Plus It's Got An Ultra-Durable Ceramic Lining For Easier Cleaning. Like All Yeti® Rambler® Drinkware, The Mug And Lid Are Dishwasher Safe.
