Impervious stretchable stockinettes are tubular limb covers made of double layer fabric that are stretchable and impermeable so they better fit on the patient's anatomy. This provides maximum sterility and barrier against fluids. In addition, to simply unroll the stockinette on the patient’s arm or leg, the stockinettes are equipped with two non-woven pulling ties. Can be used during orthopedic surgery, arthroplasty, and hand, knee, ankle, foot, extremity, and vascular procedures to isolate extremities during surgery and reduce the risk of infection.
