Abstract: A flexible shield mountable on the rump of a user's body to protect the user from incurring bruises and abrasions while sliding down a hill. The shield comprises a skid plate and adjustable straps for releasably attaching the skid plate to the rump of the user. The skid plate is preferably a sheet of flexible plastic, substantially rectangular in planform, having a smooth posterior surface for sliding on snow or ice, and having its lower portion bifurcated by a vertical slit to facilitate walking with the shield in place. A waist strap is inserted through slits in the left and right upper corners of the skid plate. Left and right leg straps secure the lower portion of the skid plate to the user's legs. A crotch strap is inserted through a slit in a flap in the lower central portion of the skid plate, the two ends of the crotch strap passing between the legs and being connected to the ends of the waist strap.
