The Ice Vino 2 Go will keep your wine chilled at the perfect temperature even on a hot sunny day while you are sipping. It is great for any place that you want to drink your wine where you may not use a glass: the pool, hot tub, the beach, etc. Fantastic for outdoor entertaining. Also keeps insects and dirt or dust from getting into your wine. Just fill it with cold water or crushed ice. You can even fill the bottom with water and put the glass into the freezer. Take it out when you are ready to "sip".
