The YETI Rambler 14 oz Mug with MagSlider Lid is the toughest, most over-engineered camp mug out there. Your hard-earned warm mug of chili after a long day deserves nothing less than 18/8 stainless steel that keeps contents hot (or cold) and hands protected thanks to its double-wall vacuum-insulated body. This mug comes with the MagSlider Lid which adds an additional barrier of protection to prevent heat or cold from escaping, but please note that the magnet component is not leakproof and will not prevent spills. Enjoy your favorite hot, or cold, drink at the right temperature with the YETI Rambler 14 oz Mug with MagSlider Lid!
