The KegSkin is constructed from neoprene and operates in precisely the same manner as its bottle-and-can-covering brethren, simply sliding over a standard-sized keg of your preferred man drink. Despite its basic construction -- take a sheet of neoprene, roll it into a cylinder and sew -- it does an impressive job of keeping beer at the optimal consumption temperature.
In a lab test, two 3°C kegs were subjected to an 26°C environment for over five hours. The insulated keg only warmed three degrees over that period (6°C is still plenty frosty) while the unprotected keg heated nearly 10 degrees in total to a flattening 13°C.
The design also has the added benefit of not requiring an outlet, as kegerators do, or tubs packed with enough ice to chill a back-alley kidney donor, which means you can drink in the park without sucking down warm suds. The KegSkin is available for in six colour varieties for $US40 from the official product site. Drop an extra Hamilton (that's $US10, shame on you for having to look it up) and KegSkin will customise your coozie with your picture or logo. [KegSkins via Geek Alerts]
