That's the large leather Cocoa Cabas. Far as I know it is completely sold out in stores.
They make a smaller version that we lovingly call the "baby cabas". My SA at Chanel calls it the Cruise Cabas. Do a search for "baby cabas" there are tons of pics.
Iluv have you been under a rock?? LOL How can you not know this bag or the baby? Girl, you need to catch up!
