A prosthetic interface comprising: a body portion including a proximal end having an open configuration, and a distal end having a closed configuration, the body portion formed at least in part by a breathable membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface, wherein the internal flow space is arranged to transport fluid through the membrane component and relative to the skin surface; and a distal cup formed of a polymeric material at the distal end of the body portion, at least one material coating (72, 74) being selectively applied to the membrane component such that the at least one material coating (72, 74) interacts with at least one of the membrane component and the distal cup to define at least one breathable region along the inner side that allows fluid flow between the residual limb and the internal flow space, and at least one impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket; characterized in that the at least one material coating (72, 74) comprises an impermeable first material coating applied to the inner side and defining a permeable region, and an impermeable second material coating applied to the first material coating, wherein a portion of the second material coating passes through the permeable region and extends between the inner side and the outer side of the membrane component to define the at least one impermeable region, the second material coating configured to bleed through the membrane component, including the internal flow space to extend between the inner side and the outer side of the membrane component. a body portion including a proximal end having an open configuration, and a distal end having a closed configuration, the body portion formed at least in part by a breathable membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface, wherein the internal flow space is arranged to transport fluid through the membrane component and relative to the skin surface; and a distal cup formed of a polymeric material at the distal end of the body portion, at least one material coating (72, 74) being selectively applied to the membrane component such that the at least one material coating (72, 74) interacts with at least one of the membrane component and the distal cup to define at least one breathable region along the inner side that allows fluid flow between the residual limb and the internal flow space, and at least one impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket; characterized in that the at least one material coating (72, 74) comprises an impermeable first material coating applied to the inner side and defining a permeable region, and an impermeable second material coating applied to the first material coating, wherein a portion of the second material coating passes through the permeable region and extends between the inner side and the outer side of the membrane component to define the at least one impermeable region, the second material coating configured to bleed through the membrane component, including the internal flow space to extend between the inner side and the outer side of the membrane component.
