Product Overview: While most things are better outdoors, it’s especially true of wine. Now, enjoying your wine in the wild is simultaneously hard core and laid back with the YETI Rambler® 10 oz. Wine Tumbler . The 18/8 food-grade stainless steel makes these puncture- and rust-resistant. Double-wall vacuum insulation keeps cold drinks cold and hot drinks hot until the last sip. Features: Like the entire Rambler® Family, the Rambler 10 oz Wine Tumbler and included MagSlider™ Lid are dishwasher-safe for easy cleaning. While the lid’s magnet adds an additional barrier of protection to keep wine in its place and at the perfect temperature, please note — this magnet component is not leakproof and will not prevent spills.
