A collapsible shield including flat spring frame and flexible sheet material. The frame substantially supporting the sheet material to form a shield. During the folding process for storage, the frames can be formed to a loop configuration by bending and having the ends of each frame held together by any suitable means such as coupling, retaining clip. The loop frames are collapsed by twisting and folding to form a plurality of concentric loop rings and layers of fabric to substantially reduce the size of the shield.
