Abstract: Disclosed herein is a surgical stockinette for covering and encasing a body extremity such as an armor leg to isolate and protect the extremity during surgery. The stockinette has a generally tubular-shape and is made from a composite material defining a length and a width with the length being longer than the width. The stockinette defines an interior surface and an exterior surface with the tubular-shaped structure defining an open end and a closed end separated by the length. The interior and exterior surfaces are joined circumferentially to one another along substantially the entire length of the tubular-shaped structure. The interior surface is formed from a fibrous material and the overall structure is liquid impervious and circumferentially expandable from a first circumference to a second and larger circumference. Due to the materials and nature of construction, the stockinette of the present invention provides a form-fitting design which is easy to don and remove.
