This is a pack of three 10" x 12" medium weight UV-Protected fabric to protect plants and vegetables from severe cold, frost & freezing rain. This fabric is easy to use and is reusable year after year. Not just for plants, it may be used for other items as well. Spread it over the windshield and windows of your compact car or truck (use two blankets for larger vehicles) on a cold night and wedge the edges in the door-frames. Remove it next morning for frost-free / snow-free windshield & windows!
