The Yeti Rambler 14oz 414ml Mug with Lid is the toughest, most durable camp mug on the market! This excellent mug has a total capacity of 414ml which is perfect for a hot coffee, hot chocolate as well as cold beverages when you're out and about. The double-wall vacuum insulation protects your hands from the internal contents and is dishwasher safe for easy cleanup. The 18/8 stainless steel is kitchen-grade which makes the Yeti Rambler 14oz puncture and rust-resistant - perfect for all outdoor activities! The wide-mouth opening makes it easy to access the contents (whether it's your drink or some oatmeal), but will cool quicker, which is why the mug includes a standard Rambler lid! It is also compatible with the Magslider Lid which allows you to cap the contents and keep them hot or cold until you are ready to consume them! The MagSlider Lid means enjoying drinks from our Rambler Tumblers without worrying about splashes on the go. Unlike other closeable drink lids, ours harness the power of magnets (yep, real magnets) for smooth opening and closing, and have a crystal clear lid so you can always see if you’re in need of a top off. Our magnet technology also makes for easy cleaning - you can pop the MagSlider off, rinse, dry, and return it to the YETI Slider Lid. And the MagSlider Lid is dishwasher safe and shatter-resistant, just like the rest of our Rambler accessories. PLEASE NOTE: Do NOT place the mug over an external heat source or an open flame. Vacuum seal or other damage may occur.
