A prosthetic system includes a liner adapted to receive a residual limb and having a liner body formed from an elastomeric material. The liner body defines an outer surface and an inner surface opposite the outer surface. The inner surface includes a first part arranged to form a seal between the liner and the residual limb, and a second part of the inner surface has at least one flow channel arranged for promoting movement of fluid away from a skin surface of the residual limb. An outlet is defined in the second part and extends between the inner and outer surfaces. The at least one flow channel is defined in the elastomeric material forming the liner body and is in fluid communication with the outlet.
