Abstract: A rain cover for a golf bag comprised of an umbrella-like cover of rain proof material for draping over the top of an otherwise opened golf bag for golf clubs (FIG. 1). The cover includes on its underside at its center an elastic sock, which is engagingly placed over the head of one of the clubs in the golf bag to hold the cover over the bag. The cover includes along its peripheral edge a hem whch has sewn within it a light chain or other flexible weight (FIG. 2A). The weighted periphery maintains the rain cover over the golf club bag in spite of winds and the like, while also allowing easy access to the user to the golf club bag by merely picking up the desired portion of the cover providing easy access into the interior. The cover cam include the elastic sock as an integral part or a pre-existing sock used in the art as a club head cover can be adapted for connection to the underside of the cover by means of for example snaps (FIG. 4A) or "Velcro" type strips (FIG. 4B).
