Abstract
A male touch fastener product with a resin surface and an array of spaced-apart male touch fastener elements carried on the surface. Each touch fastener element has a stem extending from the surface and a head disposed at a distal end of the stem and extending laterally from the stem to a distal edge overhanging the surface. The head, stem and surface form a contiguous mass of resin, the head. The distal edge has multiple toes extending laterally outward and varying in shape and size about the edge, with adjacent toes having facing, free-form resin surfaces defining crevices therebetween. The fastener element is particularly flexible and engages with very fine fibers.
