Stool Equipment Rain Cover Tested at Camp Perry and it works. This cover was designed so that the shooter can saddle his rifle and shooting equipment on the shooting stool and by means of this compact rain cover protect his gear form the weather and exposure to accidental tampering. The cover is made out of nylon pack cloth. It slips over the shooting equipment and stool and is secured by means of a strap that goes under the stool and attaches to the other side of the cover. Please note: the blue cover is now a different material. It is a water proof material (more like a plastic).
