Transparent and water-resistant Ralph Lauren bag - now the United States Open signature bag as well – has been increasingly becoming popular since its debut at last year's tournament.
The plastic bag with a blue drawstring closure now comes free with every purchase at the Ralph Lauren boutique at the Billie Jean King National Tennis Center in Flushing, N.Y.
Shoppers are asking for extra bags for giving them as compliments to near and dear ones, who put the logo bags to different uses.
Some use it as a beach bag, a gym bag, a tennis bag and a book bag, while others use the plastic duffel as protective wrap for their purses and carrying cases for their Polly Pocket dolls.
There are still others who love to cherish the bag as keepsake just for the beauty of it.
