Poorti breast prosthesis is manufactured in a clean set-up with HEPA purified air using medical grade silicone and a medical-grade polyurethane film. The breast prostheses are to be first put into a prosthesis cover and then placed inside the pocket of the supplied bra. Therefore there is no direct contact of the prosthesis with the skin. Only cotton makes direct contact with the skin and we use very high-quality cotton material to manufacture our pocketed bras.
