An apron for use in shoeing horses or in other activities in which there is a likelihood that a tool might puncture the thigh portion of a person's clothing has detachable thigh pads. The apron is washable, air permeable and lightweight in comparison to the pads. The pads, preferably leather, are puncture resistant, identically shaped and symmetrical about vertical and horizontal axes. The attachment mechanisms, such as mating segments of hook and loop material, are positioned so that the pads are interchangeable on the coverings. Thus, damaged pads can be rotated, switched or replaced on one lightweight apron, maximizing pad use and minimizing packing space for travel.
