Presenting a Loungefly mini backpack that's automatic, systematic, hyyy-dromatic â it's Greased Lightning in bag form. Inspired by the iconic leather jackets worn by Danny, Kenickie and the T-Birds, this faux leather cosplay-style mini backpack nails every detail. Finished with metal rivets, a moulded zipper charm and a mix of applique, embroidered and printed elements, it's the perfect way to show your T-Bird pride â without needing your own set of wheels.
