The YETI Rambler 30 oz. tumbler is designed to keep your beverages at their ideal temperature throughout the day. Made with kitchen-grade stainless steel and double-wall vacuum insulation, this tumbler protects your drink from both external temperatures and ensures that your morning coffee stays hot and your iced coffee stays cold. The MagSlider Lid, included with the tumbler, features a magnet that makes for easy opening and closing, while also adding an additional barrier to prevent heat or cold from escaping. The 30 oz. tumbler, made of 18/8 stainless steel, is shatter-resistant and dishwasher safe for easy cleaning. Its size makes it perfect for taking on the go, and the Rescue Red color adds a stylish touch. This tumbler is suitable for both men and women.
