Found this cool insulated cover at Wal-Mart. Fits the standard plastic, round toy basket. 6 gallon Better Bottle fits perfectly along with a couple bottles of ice. Seems to work well as room temp is 75, temp inside dropped to 62. Top has a zippered hole so the neck of your carboy is sticking out for your blow-off tube or airlock. Best thing, it was on the clearance shelf for eight bucks. Can't wait to try it on my next brew.
