This is the model before Longchamp's Neo line, both of which I believe are now discontinued. This line (Les Planetes) has a smooth, more satin-like finish on the nylon as well as on the leather, making it an extra polished work bag that can also easily be dressed down for more casual events. The nylon is durable but has a surprisingly smooth and soft touch to it. The leather, too, is strong and soft to touch! Very sturdy bag and I am really impressed by how functional it is! Unfortunately, I really need to clean out some items in my closet...and I hope this gorgeous bag find a new home where it can be appreciated more! Let us know if you have any questions!
