The YETI Rambler® 414 ml / 14 oz Mug is the toughest, most over-engineered camp mug out there. Unlike traditional camp mugs, this double-wall vacuum-insulated body protects hands from hot or cold contents while keeping coffee, chili, oatmeal – you name it – well-insulated. Like all Rambler Drinkware, the 414 ml Mug and its lid are dishwasher safe making it easy to clean. The mug’s wide opening means contents are easily accessible but will cool quicker.
