Differences between Navona and Damier Pochette?

Someone did a comparison of the pochette (mono) and the navona (I think ayla did it). The pochette accessories is longer, but the navona is a bit wider and has a longer strap. :smile:
 
The reason for the price difference is because the Navona has a strip of leather running along the sides and bottom of the pochette, hence the higher price.
