Yes, refrigerated panties exist. Japan is currently suffering a heat wave, and residents need a way to keep cool. These undies are packaged in plastic cups that looks like bubble tea cups. The whole package is then put into the fridge.
You can buy these refrigerated panties at 'M's Tower' in Tokyo. They will cost you less than $15 to keep your lower half cool during a hot summer day. Whether or not the undies keep you cool for the whole day has yet to be discovered.
