A strip material from which a portion may be severed to form a portion of a fastener. The strip material comprising a polymeric bonding layer; a multiplicity of flexible, resilient, generally U-shaped monofilaments, each monofilament including a central elongate bight portion embedded in the bonding layer, two stem portions extending from the opposite ends of the bight portion and projecting generally normal to an exposed major surface of the bonding layer, and enlarged heads at the ends of the stem portions opposite the bight portion, resiliently elastic material attached to the surface of the bonding layer opposite its exposed major surface, and pressure sensitive adhesive means along an attachment surface of the resiliently elastic material opposite the bonding layer for adhering the strip material to a substrate. The combination of the bonding layer, the monofilaments, the layer of resiliently elastic material and the pressure sensitive adhesive means are highly transparent when viewed from an angle at which the exposed major surface of the bonding layer can be seen after strip material is adhered to a substrate so that the color of the substrate will be fairly clearly seen through the strip material.
