A suspension liner sleeve (210) is provided which may be used as an interface between a residual limb and a prosthetic socket. The liner sleeve (210) includes an elongate, generally conical body portion formed from at least first and second material segments (212, 214) defining a liner outer surface. The material segments (212, 214) are at least radially elastically extensible from a relaxed non-extended condition and define proximal and distal end areas. A single (118) or plurality of resilient seal elements (228) protrude(s) radially from the liner sleeve outer surface. The single (118) or plurality of seal elements (228) extend(a) around a peripheral portion of the liner body portion.
