Abstract: A liner for a prosthesis, which liner has a proximal opening, for receiving an amputation stump, and a distal end lying opposite the proximal opening. The liner is produced from a liner material, wherein a longitudinal direction of the liner extends from the proximal opening to the distal end, and a circumferential direction runs perpendicular to the longitudinal direction. The liner has a plurality of fibers, which are made from an inelastic material and are arranged in such a way that a lengthening of the liner in the longitudinal direction results in a shortening of the liner in the circumferential direction, and vice versa. The liner has non-slip features which, when the liner is fitted in place, prevent the liner from slipping on the amputation stump.
