The YETI Rambler® 14 oz Mug is the toughest, most over-engineered camp mug out there, because your hard-earned warm mug of chili after a long day deserves nothing less. 18/8 stainless steel keeps contents hot (or cold) and hands protected. Find a color that calls to you. The mugs are available in stainless steel, and in DuraCoat Color. The mug comes with the standard Rambler 30 oz Lid but is also compatible with the Rambler 30 oz MagSlider Lid.
