The Hi-viz Exercise Sheet made by Medway/Sheldon has a waterproof outer and a fleece lining, perfect for cold, wet, winter days. The sheet features a fillet string and reflective strips on the tail flap and back quarter to increase visibility in dark conditions. The rug can either be worn under the saddle or wrapped around over the top for ease. There is a large velcro fastening at the front and stirrup straps for when worn under the saddle.
