Abstract: A golf bag cover for protecting golf clubs during inclement weather is disclosed. The cover of this invention keeps clubs dry while in the bag, and, in addition, provides easy access and an unobstructed view thereof to facilitate selecting a club for play during such weather. The cover of this invention is a tubular sleeve of water impervious, preferably transparent, material having a frustoconical shape. A band of elastic surrounds and gathers the base and the top portions thereof in pleats, and the sleeve is sufficiently elongated so that when the base is fitted over the mouth of the bag, the upper portion of the cover will fold over the club heads. A club is then removed from the bag or returned thereto through the top of the cover. The cover of this invention is preferably constructed of crushable or non-selfsupporting plastic so that it may be collapsed to a compact package for storage.
