Abstract: A cover at least partially protects at least one item from one or more falling objects. An exemplary embodiment provides a flexible cover having a top side and a bottom side and a perimeter; a plurality of fluid-filled pockets dispersed along the bottom side of the cover; a channel formed around the perimeter of the cover material to house a drawstring, the channel having an opening that exposes at least a portion of the drawstring; and a drawstring disposed within the channel, wherein the cover positioned over an item may be selectively at least partially secured in position by pulling on the drawstring through the channel opening. Alternative embodiments provide selectively inflatable bladders and side drape portions and kits therefor.
