While most things are better outdoors its 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 Coolers 10 oz. Wine Tumbler is the YETI answer to the wineglass 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.
