While most things are better outdoors, it's especially true of wine. But that simple pleasure demanded some serious engineering to ensure no pool deck, happy hour, or boat is hampered by broken glass. YETI's 10 oz. Insulated Wine Tumbler is YETl's answer to the wine glass and is available in stainless and DuraCoat colors. Like the entire Rambler Family, the Wine Tumbler and included MagSlider Lid are dishwasher safe for easy cleaning. The smooth-sliding lid adds an additional barrier of protection to keep your wine contained, at the perfect temperature, and safe from thirsty flies. Note: This magnet slider is not leakproof and will not prevent spills.
