1. A fastener product comprising a base;
- and an array of fastener projections extending integrally from a first surface of the base, the projections each comprising a stem portion of resin molded integrally with the first surface of the base, and a head portion disposed at a distal end of the stem portion and configured to releasably engage a complementary fastener element to form a fastening;
wherein the stem portions of the fastener projections and at least a portion of the base are integrally formed of a single resin; and
wherein at least a portion of the single resin of the base is in a foamed state.
