Abstract: A cargo bed cover in which two frames are used to provide a rigid fabric shell. The first frame is rigid and is constructed of metal piping or other suitable material. The second frame is constructed of flexible stock preferably having a substantially flat cross section and sewn into or secured to the fabric material. Acting as battens, the flexible stock tends to keep the fabric taut during wind pressure either through ambient conditions or through the vehicle's movement. The flexible frame is secured to the rigid frame through ties.
