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! PLEASE NOTE: The Rambler 14oz Mug comes with the standard lid. Magslider Lid sold separately. Do NOT place the mug over an external heat source or an open flame. Vacuum seal or other damage may occur.
