The Yeti Rambler 10 oz (295ml) Stackable Mug With DuraSip Ceramic combines double-wall vacuum insulation with an 18/8 stainless steel body and a DuraSip Ceramic interior lining - a non-stick, stain-resistant surface fused directly to the steel that delivers a clean, neutral taste and a smooth lip feel without affecting the temperature performance of the insulated vessel. The ceramic lining resists staining from coffee and other acidic beverages, making the mug straightforward to clean even with daily hot drink use. A 360-degree welded handle provides a firm, comfortable grip, and the stackable base nests with other mugs of the same size or smaller to save bench and storage space. The MagSlider Lid provides a splash-resistant seal for carrying in transit, and both the mug and lid are dishwasher safe. All materials are BPA-free, and the mug is backed by a five-year warranty.
