Claim 14:

a resin surface;
an array of spaced-apart male touch fastener elements carried on the surface, each touch fastener element extending to an overall height above the resin surface and comprising
a stem extending from the surface; and
a head disposed at a distal end of the stem and forming with the stem and the surface a contiguous mass of resin, the head extending laterally from the stem to a distal edge overhanging the surface about the stem, the distal edge extending toward the surface and defining a minimum edge height above the surface;

wherein the head defines a head return equal to a difference between the overall height of the fastener element above the resin surface and the minimum edge height above the surface; and
wherein for each of at least most of the fastener elements of the array, the fastener element has an umbrella ratio, defined as a ratio of the head return to the overall height of the fastener element above the resin surface, of between about 0.2 and 0.5.
