The Rambler 14 oz. Mug is one of the toughest, most over-engineered camp mugs 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 14 oz. Mug and lid are dishwasher safe making them easy to clean. The mug’s wide opening means contents are easily accessible, but will cool quicker.
