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. The vacuum secures the socket to the liner and the liner to the residual limb of the user.
