I CAN'T FIND THIS PARTICULAR MODEL OR DESIGN ANYWHERE ON EBAY OR GOOGLE PICS.  AS PICTURED IT STATES UPPABABY VISTA ON THE BAG.  THIS DESIGN LOOKS LIKE YOU UTILIZE THE WHEELS OF THE STROLLER TO ROLL IT AROUND IN THE BAG.  PLEASE SEE PICS.  I HOPE SOMEONE CAN TELL ME EXACTLY WHAT THIS IS.  IT WAS A RECENT ESTATE PURCHASE.  IT HAS ANOTHER ROUND COVER THAT WAS INSIDE OF THEBAG.  IT LOOKS LIKE IT IS MISSING A SHOULDER STRAP AS THERE ARE HOOKS FOR ONE.  PLEASE ASK ANY QUESTIONS AND THANKS FOR LOOKING
