Z.A.S.K. is an acronym for 'zombie apocalypse survival kit'. While a zombie apocalypse is a remote possibility, the Z.A.S.K. also serves as an all-purpose survival kit for hurricanes, earthquakes, and floods -- as well as the occasional zombie apocalypse.
Just ordered a second Z.A.S.K. for the car, complete with 3-day food supply for two, a multi-function knife, and iodine tablets for water purification. One never knows when zombies will strike.
