Abstract: A foldable or flexible wrap is disclosed herein having a pair of plastic-like sheets selectively joined together at critical locations so as to provide fold lines or paths subject to flexure whereby the wrap may be wound about an article intended to be maintained in a cool environment. One sheet of the pair is flat while the other is provided with a plurality of spaced-apart pockets containing a freezable gel or substance, such as water. The pockets are arranged in a defined pattern adjacent to the fold lines or paths so that the wrap may take many different configurations when folded about articles of different shapes and sizes.
