The YETI Rambler® 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 and whatever else you put in it well-insulated.
Important: Do not place mug over external heat source or open flame. Vacuum seal or other damage may occur
