Ever try to enjoy your favorite whiskey/scotch/cocktail on the rocks at the end of the day, only to feel rushed to finish it before the ice melts? You'll love the AVEX Sundowner, a vacuum-insulated, no-sweat, stainless steel rocks glass that regulates temperature in a way that keeps ice cold for hours. The rubberized bottom prevents any sliding around and protects any surface you set the glass down on.

Though it's made for hard drinks in particular, it also works great for coffee in the morning and even for eating ice cream. Get it for $19 on Amazon.
