Abstract: An impermeable golf bag cover is fabricated from a flexible, transparent and impermeable material to protect the interior of the golf bag and the enclosed clubs from inclement weather when a club is being removed from the bag or replaced into the bag. The lower bottom portion of the golf bag portion is used both to secure the cover to the open top of a golf bag while the remaining portion of the lower bottom portion serves as an access portion to the interior of the golf bag and its contents. An extended tubular upper portion of the cover is integral to the lower bottom portion and has sufficient length to accept a golf club during the procedure of its removal from or replacement into the golf bag.
