Equinventions Croup Cover This is a monthly column featuring new inventions and gadgets related to horses. We invite your submission and suggestions. Trail riders will appreciate this sturdy net over the back of their horse during the season of biting horseflies and stinging insects. The Croup Cover is breathable and will not shift when pinned with a blanket pin to the back of a saddle pad.
