Abstract: A removable liner used in conjunction with a socket for a prosthetic device, in which a vacuum is wicked across the entire area of a porous fabric of the liner, is disclosed. The liner preferably includes a shaped-layer made from one of either a silicone or a urethane and has an exterior surface, an interior surface and a passage therein which opens at each of the two surfaces and connects to a valve of the socket. The liner further includes a first porous fabric covering at least a portion of the exterior surface of the shaped-layer including the corresponding opening of the passage, and a second porous fabric covering at least a portion of the interior surface of the shaped-layer including the corresponding opening of the passage. A vacuum source coupled to the liner, via the valve on the socket, draws a vacuum which is wicked across the entire surface of the first and second porous fabrics which interface with the socket and the user's residual limb, respectively.
