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.
