Winner Thermos ! (it’s COMFORTABLE TO HOLD, no top to lose, and 1/3 the price of Yeti) So I did a test with a Yeti, Thermos, Coleman style, thick foam, and neoprene koozie…and nothing at all as a control. I chilled 6 cans to 34°. Each had exactly 8 ounces of water. (didn’t want to waste beer…or drink that much) Why 8 ounces you might ask. No one opens a soda or beer and doesn’t have at least a sip or 2 before forgetting they have it. For all you complaining that it doesn’t fit a non-standard can….Quit your whining. Manufacturers can’t make something that fits everything. This was a standard can test. In a 72 degree room. I know that’s not the 90 you would prefer, but it doesn’t matter as a test of which ones are the best. What matters is having exactly the same conditions for every can. After 15 minutes – No insulation was 41°, Foam, Coleman and Neoprene were 37°, Thermos and Yeti were 35° After 30 minutes - Nothing was 51°, Foam, Coleman and Neoprene were 41°, Thermos and Yeti were 36° After 50 minutes - Nothing was 55°, Foam, Coleman and Neoprene were 44°, Thermos and Yeti were 38° After 120 minutes - Nothing was 60°, Foam, Coleman and Neoprene were 49°, Thermos and Yeti were 40° As far as temp is concerned the Thermos and Yeti were tied. And both FAR superior to the old stand by neoprene........... Seven year update..... STILL THE BEST ONE OUT THERE.... PERIOD !!!! (for a standard can) my only complaint might be is when I think I have one sip left ....nothing because on the added weight. I've tried a few more vacuum insulators, ones that say they hold all sizes, but they just don't work as well (all things considered like tip over propensity, fussing with a cap, feel in your hand....and of course insulation)
