For maximum resistance, these AAMI PB70 standard approved Fully Reinforced Surgical Gowns are made of strong and durable non woven materials. They are designed to prevent infectious agents from being transmitted between clinical staff and patients during surgical and other invasive procedures, either with high and low risk of infection and penetration by liquids. They can be used by both patients and clinical staff and are secured at the neck with a strap to improve usability.
