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. The 10 oz. Insulated Wine Tumbler is YETI's answer to the wine glass. 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. Made with kitchen-grade stainless steel.
