The Artican seems like the best hardcore way to keep canned drinks cold. It features two layers of vacuum-insulated steel and an ice-filled “cooling core” that screws into the bottom. The result is that it will keep your 12 oz. beers three times colder for three times as long as the average foam Koozie.
We’re talking cold drinks for up to three hours in the sun. The core is filled with a “proprietary freezing gel” that has a high specific heat coefficient. That means that it can absorb a lot of heat before it starts to actually warm up. While $20 seems like a lot for a can cooler, but if you really love beer it’s worth it.
Besides, we all hate lukewarm beer. And on a hot day, a cooler like this makes all the difference.
