You guys seem to be in the know - does something like this exist in a double walled/vacuum insulated way? I'd be interested in getting one for dinners with friends, but I'm not counting on neoprene to keep the beer cold for very long.
JohninBrooklyncan't put double walled in a fridge.
I'd be more interested in some kind of way to strap ice or cold packs to this, and keep them insulated as well.
