If you’re sick of warm beer ruining a great summer’s day, then the Corkcicle Arctican ($20) is a must. Forget all about those foam rubber Koozies that really don’t do anything. The Arctican will keep your drinks cold without making your hands cold. Two layers of vacuum insulated stainless steel keeps the heat out and the cold in, but the Arctican has one more trick up its sleeve. The Twist-On cooling core is filled with a proprietary freezing gel, that keeps drinks cooler longer. How long? It will keep your drinks cold for up to 3 hours. In three hours, you should be able to put a nice dent in that case.
