But that simple pleasure demanded some serious engineering to ensure no pool deck, happy hour, or boat is hampered by broken glass. Our 10 oz. Wine Tumbler is the YETI® answer to the wine glass and is available in stainless steel 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 and at the perfect temperature, but please note — this magnet component is not leakproof and will not prevent spills.
