A tailgate barrier for closing the open end of a truck bed is a rectangular sheet of substantially inelastic flexible material held as a membrane in bi-axial tension by continous elongated upper and lower edges extending to a tension strap at top and bottom corners of each end, the membrane being provided with a pattern of perforations, each of which is in the form of a generally U-shaped slit wherein the central portion of the U is a depending flap that flexes out of the plane of the membrane during the passage of air flow through the membrane. A preferred embodiment has an arcuate tension member connecting the top and bottom corner at each end. Another preferred embodiment has printed indicia that extends across the membrane and at least some of the depending flaps of the perforations.
